I found the top 50 words in all the #1 pop hits listed in Billboard magazine from 1965 to 2015.

Filtered:

im, like, oh, dont, love, know, got, baby, get, yeah, youre, go, wanna, cause, make, want, girl, never, one, let, see, gonna, aint, cant, la, come, ill, back, time, feel

Then I put them together into (semi-)meaningful lyrics.

I'm like, oh don't love know

I got a baby, yeah

You're gonna wanna want me

Cause you make me, girl,

Never be the one to let me see

I ain't the one

Can't be —la la la—

the one to come back.

I'll take time to feel it.
