Are you serious? If Creed's lyrics are mediocre, you have been hanging around planet Uranus way too long.
They have awesome lyrics, one of the best of any band if not THEE best, IMO. I'm not familiar with "underground" hip-hop, didn't know there was such a thing, but if it's anywhere near regular hip-hop, there is no comparison to Creeds which are far more outstanding.
I mean does "Hurray for a child that makes it through, if there's any way, because the answer lies in you" compare to "Back Dat Ass Up"? I don't think so.
Does "It's funny how silence speaks sometimes when you're alone, And remember that you feel" compare to "Get Jiggy with it" or "Shake dat thang". I don't think so.
Just my opinion though.
