Thered better be a mirrorball lyrics

I think you might be thinking of the song "There's a Better Way" by the band Red Hot Chili Peppers, but it's actually called "There Hasn't Been a Day" and it doesn't have the lyrics "thered better be a mirrorball".

However, I think you might be thinking of the song "Mirrortone Baby" by the band Red Hot Chili Peppers, which is from their album "One Hot Minute". The lyrics to that song are:

"Mirrortone baby, you're a star You're a shining light, from near and far You're a shining light, from near and far Mirrortone baby, you're a star"

Let me know if that's the one you were thinking of!
