1989年底，Ice Cube怀疑Eazy-E和他的经纪人杰瑞·海勒（Jerry Heller）控制了N.W.A的收入（同样的，也因为他认为自己写了很多歌词，却没有得到应有的回报），提出了索赔请求，并且于1990年初正式离队，并且还控告杰瑞·海勒向其他成员隐瞒了这件事。　不过，令人感到惊奇的是，Ice Cube在处子专辑《AmeriKKKa Most Wanted》中并没有直接攻击N.W.A，虽然还是有一些隐晦的攻击。

Ice Cube在1990年7月1日发行了EP专辑《Kill At Will》，对这件事大肆宣扬，包括了 《Jackin' For Beats"》和 《I Gotta Say What Up!!!》。在 《I Gotta Say What Up!!!》中，Ice Cube高度讚扬了期的说唱同行，包括Pubic Enemy，Geto Boys，Sir Jinx，Kool Moe Dee，LL Cool J，Africa Bambaataa，EPMD，King Tee，Yo-Yo，Ice-T，Compton's Most Wanted，Too Short，Stretch，King Sun，Busy Bee，Run-D.M.C.，Big Daddy Kane，DJ Pooh，The Bomb Squad，Digital Underground，他的堂弟Del the Funky Homosapien等等，而在歌曲，有一段类似与採访的音频，Ice Cube被这样问道“自从你单飞后，你以前的队友怎幺样了？（Since you went solo, whatever happened to the rest of your crew?）随后採访便突然被掐断了。

1990年，N.W.A在他们的发行的EP专辑《100 Miles and Runnin'》中的同名歌曲包含了一段对Ice Cube的侮辱，“我们以五个人开始，但一个人不能继续坚毅；所以现在是四个人，因为第五个不能继续做专辑。（We started with five, but yo / One couldn't take it—So now it's four / Cuz the fifth couldn't make it.）”　歌曲的MV临近结尾处有一幅画面描绘了N.W.A的四个成员在一个形似Ice Cube的释放的时候被警察逮住关在监狱中，并最终逃脱。EP中的另一首歌曲《Real Niggaz》则可以说是对Ice Cube的辱骂的全面爆发，N.W.A剩下的4个成员斥责了Ice Cube的懦弱，真实性，歌曲的长寿度和独创性“你觉得一个说唱艺人该怎样继续？喔，是要像你一样放着屁说着过去；搞搞清楚，你的歌软弱无力！赶快滚，你这中途逃离的狗屁！”（How the fuck you think a rapper lasts / With your ass sayin' shit that was said in the past / Yo, be original, your shit is sloppy / Get off the dick, you motherfuckin' carbon-copy," ）和“我们开始时有着太多的人，现在我很庆幸拜託了你这个本笃·阿诺德（本笃·阿诺德，一个美国独立战争时靠拢英国的叛徒），哟！”（ "We started out with too much cargo / So I'm glad we got rid of Benedict Arnold, yo）

在1990年9月，Ruthless旗下的团体Above the Law在位于纽约的时代广场（Time's Square）的马奎斯万豪酒店的年度新音乐研讨会（New Music Seminar）上与Ice Cube的团体Da Lench Mod发生冲突，并且迫使后者狼狈地逃离现场。

而N.W.A的第二张正式专辑《Niggaz4Life》中便更加直白。在插曲《A Message To B.A.》中，N.W.A.成员把Ice Cube比作Benedict Arnold（本笃·阿诺德），一名美国革命时期American Revolution的叛徒，并在结尾处破口大骂。，对Ice Cube计画自己的处子专辑《AmeriKKKa Most Wanted》的製作团队将是来自纽约长岛的The Bomb Squad（也是Public Enemy当时的御用製作组）一事进行了讽刺，称其是“舔纽约人的阴茎”（"...sucking New York dick",）。插曲 《A Message to B.A."》也回应了回应了《AmeriKKKa's Most Wanted》中的《Turn Off the Radio》的开头。Ice Cube一开始还只是被称为本笃·阿诺德，后来更是被N.W.A剩下的成员和N.W.A的冬粉大肆辱骂，包括MC Ren在插曲结尾的这一段话当门看见你（的黑皮股）是，我幺剪断你的头髮并用扫帚猛揍你。怎幺样？蠢货？（When we see yo' ass, we gon' cut yo' hair off and fuck you with a broomstick. Think about it, punk muthafucka）1991年，Ice Cube在电影《Boyz N the Hood》中担任主角。他嚮导演约翰·辛格顿（John Singleton）建议，把一个绑架犯绑架两个青少年的场面中的绑架犯进行绑架时的髮型变成杰瑞捲髮（Jheri curl，Eazy-E的髮型，流行于二十世纪八十年代的非裔黑人中），并且加上一副墨镜和《We Want Eazy》的宣传衫。　I

Ice Cube和N.W.A的纷争最开始升级，包括歌曲和现实当中。《AmeriKKKa's Most Wanted》这张专辑中，Ice Cube避免了和N.W.A剩下成员的冲突，但他的第二张正式专辑中，《Death Certificate》，Ice Cube开始了他的报复。他採样并嘲笑了插曲《A Message to B.A."》，并在臭名昭着的辱骂歌曲——《No Vaseline》中採样后使用。Ice Cube在歌词中猛烈地报复了N.W.A“你们看起来就像鲁莽的笨蛋，我发现了所以我就单干；我有了自己的公司，你们就开始嫉妒，但我是真汉子，没人可以像我一样急速。（You lookin' like straight bozos / I saw it comin' that's why I went solo / You got jealous when I got my own company / But I'm a man, and ain't nobody humpin' me”）”Ice Cube同样回应了《100 Miles and Runnin‘》“一开始有太多无用的货，我丢下四个黑鬼；于是我赚到了所有的家伙。（ I started off with too much cargo, dropped four niggaz / And now I'm makin' all the dou）”而Eazy-E，Dr. Dre，MC Ren分别被Ice Cube用同性恋隐喻了他们与经纪人杰瑞·海勒（Jerry Heller）之间的关係轻鬆地摆脱那恶魔，瞄準他的颞颥；你们不能成为“黑鬼人生”的团队，因为告诉你们怎幺做的人是个白犹太。（Get rid of that devil real simple / Put a bullet to his temple / Cuz you can't be the 'Niggaz 4 Life' crew / With a white Jew tellin' you what to do.）”他还把N.W.A的成员称为骗子"phonies"，还宣称Eazy-E打小报告（"snitch"）。歌曲因为他的基于对海勒的宗教信仰的反犹太主义 （antisemitism）而备受争议（即指责Ice Cube与伊斯兰国度的从属关係）。这首歌在英国发行专辑时被去掉，製作了它的审核后版本。

这一纷争由Ice Cube的大获全胜告终，换来了自己的名声大噪和N.W.A的解散。

Got damn, i'm glad ya'll set it off.

Used to be hard, now you're just wet and soft.

First you was down with the ak,

And now i see you on a video with michel'le?

Lookin' like straight bozos.

I saw it comin', that's why i went solo.

And kept on stompin',

When ya'll mothafuckers moved straight outta compton.

Livin' with the whites, one big house,

And not another nigga in site.

I started off with too much cargo,

Dropped four niggas now i'm makin' all the dough.

White man just rulin'.

The niggas with attitudes -- who ya foolin'?

Ya'll niggas just phony,

I put that on my mama and my dead homeys.

Yella boy's on your team, so you're losin';

Ay yo dre, stick to producin'.

Callin' me arnold, but you been-a-dick;

Eazy e saw your ass and went in it quick.

You got jealous when i got my own company,

But i'm a man, and ain't nobody helpin' me.

Tryin' to sound like amerikkka's most,

You could yell all day but you don't come close.

Cuz you know i'm the one that flown,

Ya done run 100 miles, but you still got one to go.

With the l-e-n-c-h m-o-b, and ya'll disgrace the c-p-t.

Cuz you're gettin' fucked out your green by a white boy,

With no vaseline...

[refrain] (l.l. sample: 'now you're gettin' done without vaseline...')　3x

(biz markie sample: 'damn, it feels good to see people...on it')

The bigger the cap, the bigger the peelin',

Who gives a fuck about a punk-ass villain?

You're gettin' fucked real quick,

And eazy's dick, is smellin' like mc ren's shit.

Tried to tell you a year ago,

But willie d told me to let a hoe be a hoe, so

I couldn't stop you from gettin' ganked,

Now let's play big-bank-take-little-bank.

Tried to dis ice cube, it wasn't worth it

Cuz the broomstick fit your ass so perfect.

Cut my hair and i'll cut them balls,

Cuz i heard you're, like, givin' up the drawers.

Gang-banged by your manager, fella,

Gettin' money out your ass, like a mothafuckin' ready teller.

Givin' up the dollar bills,

Now they got the villain with a purse and high-heels.

So don't believe what ren say,

Cuz he's goin' out like kunte kinte,

But i got a whip for ya toby;

Used to be my homey, now you act like you don't know me.

It's a case of divide-and-conquer,

Cuz you let a jew break up my crew.

House nigga gotta run and hide,

Yellin' compton, but you moved to riverside.

So don't front, mc ren, cuz i remember when you drove a b 2-10.

Broke as a mothafuckin' joke.

Let you on the scene to back up the verse team.

It ain't my fault, one nigga got smart,

And they rippin' your asshole apart.

By takin' your green, oh yeah,

The villain does get fucked with no vaseline.

[refrain scratched]

I never have dinner with the president.

I never have dinner with the president.

I never have dinner with the president.

And when i see your ass again, i'll be hesitant.

Now i think you a snitch,

Throw a house nigga in a ditch.

Half-pint bitch, fuckin' your homeboys.

You little maggot; eazy e turned faggot.

With your manager, fella,

Fuckin' mc ren, dr. dre, and yella.

But if they were smart as me,

Eazy e would be hangin' from a tree.

With no vaseline, just a match and a little bit of gasoline.

Light 'em up, burn 'em up, flame on...

Till that jheri curl is gone.

On a permanent vacation, off the massa plantation.

Heard you both got the same bank account,

Dumb nigga, what you thinkin' bout?

Get rid of that devil real simple, put a bullet in his temple.

Cuz you can't be the nigga 4 life crew

With a white jew tellin' you what to do.

Pullin' wools with your scams, now i gotta play the silence of the lambs.

With a midget who's a punk too,

Tryin' to fuck me, but i'd rather fuck you.

Eric wright, punk, always into somethin', gettin' fucked at night.

By mista shitpacker, bend over for the gotdamn cracker, no vaseline...

作为美国洛杉矶着名说唱组合N.W.A的核心成员之一，Ice Cube也是该组合中最早宣布单飞而谋求个人发展的成员。在离开N.W.A组合之后，Ice Cube逐渐成长为美国Hip-Hop音乐界最优秀也是最具争议的歌手之一。Ice Cube在他个人发展之后的专辑中表现出了更为尖锐的政治和社会观点，这也使得他颇为引人注目的前两张个人专辑《AmeriKKKa??s Most Wanted》和《Death Certificate》毁誉参半。后来，Ice Cube开始和Cypress Hill等后辈说唱乐团合作，其本人的影响力虽略有下降，但Ice Cube在整个美国说唱界的地位却从未改变。在上世纪90年代，Ice Cube一直都是最耀眼的说唱歌手之一。与众多家境贫寒，从小便浪迹街头的说唱歌手相比，Ice Cube的家境算是比较好的了。原名O??Shea Jackson的Ice Cube从小生活在洛杉矶的中南部，父母都在加州大学洛杉矶分校（UCLA）工作，而少年时期的Ice Cube也一直都是个好孩子。到了上中学的时候，Ice Cube才开始创作Rap，而他在这个时期创作的歌曲包括了与搭档 Sir Jinx合作写出的《Boyz-n-the Hood》。随着创作水平的不断提高，由Ice Cube领衔的二人说唱组合“CIA”开始在Dr.Dre举办的排队上演出。很快，Ice Cube就通过Dr.Dre结识了当时还在HBO组合的Eazy-E。随后，Eazy-E决定离开HBO。事实上，在这个时候，Eazy-E，Dr.Dre和Ice Cube三人已经构成了N.W.A组合的雏形。1987年，Ice Cube前往菲尼克斯学习建筑。1988年，在拿到了一年制的学位之后，Ice Cube重新回到了洛杉矶。而Ice Cube的这次回归正是时候，因为他正好赶上了N.W.A组合首张专辑《Straight Outta Compton》的录製。最终，《Straight Outta Compton》在1988年末发行并成为1989年美国地下说唱圈中的热门专辑。专辑歌词中的极端内容得到了各界的关注，其中最引人注目的是美国联邦调查局（FBI）对本张专辑的关注。由于Ice Cube和N.W.A的经纪人有着很严重的分歧，他在1989年末的时候选择了离队。
