美国有一个古老的迷信彩虹是梦想与希望的象徵，当彩虹出现时会带来幸福。Mariah Carey本人表示，专辑会取这名字完全是意外，其实直到开始录製专辑时，她还完全不知道该如何命名。但就像上帝的指引般，那天的录音特别不顺利，当她因为录音的疲倦步出录音室外时，突然看见到天空有两道彩虹，那两道彩虹比起以往所见的彩虹还绚丽夺目。看到那些鲜艳幸福的色彩时，她感到极大的感动，玛丽亚凯莉表示过去一年来，有许多事情的发生让自己的心情起伏不定，她相信彩虹所能带来的幸福。玛丽亚凯莉还表示，一个完美的世界应该如同彩虹般，虽然有不同颜色的存在却能和谐共存，便命名该专辑为《Rainbow》。

When I think of our untimely end

And everything we could have been

I cry, baby I cry

Ok so it's 5 am and

I still can't sleep

I took some medicine

But it's not working

Someone's clinging to me

And it's bittersweet

'Cause he's head over heels

But it ain't that deep

I finally changed my number

Got a different pager

Then last Saturday

Your cousin called to say you're

Tryin' to reach me

Probably because you see that

I'm with someone new

Late at night like a littie child

Wandering around alone in my new friend's home

On my tippy toes

So that he won't know

I still cry baby

Over you and me

Sipping Bailey's Cream

By the stereo

Trying to find relief

On the radio

I'm suppressing the tears

But they start to flow

'Cause the next song I hear

Is a song I wrote

When we first got together

Early that September

I can't bear to listen

So I might as well drift

In the kitchen

Pour another glass or two

And try to forget you

Late at night like a littie child

Wandering around alone in my new friend's home

On my tippy toes

So that he won't know

I still cry baby

Over you and me

SNOOP'S VERSE

Late at night like a littie child

Wandering around alone in my new friend's home

On my tippy toes

So that he won't know

I still cry baby

Over you and me
