I pretty much suck at writing lyrics and can't write something not cheesy no matter how hard I try. If I however do write something good it usually turns out that the exact same thing, or something similar, was written 20 years before me.
My favorite lyricist has to be Neil Peart. He writes such good stuff it's unbelievable.
I pretty much love almost anything he's ever written.
As far as most hated I'd have to say the kinda stuff that's basically just repeating five words over and over and anything Fergie has ever sung.
I'm not too big on the "brag"-rap lyrics when they say how big their rims are or how many women they have swimming in their pool filled with money.
Good topic btw
