Well, since I just said this five minutes ago on
@BlueHammer85's top 100 songs thread, I'll repeat it here . . .
"All about opinions, but I think Radiohead are far and away the most overrated band in the history of popular music. To me they're nails on a chalkboard. The voice, the lyrics, the sodden tempos, the whining, the hookless-ness, the songs that never seem to end, the drowning in atmospherics. I have absolutely never understood their appeal."
I also think Bob Dylan is overrated but his music isn't my style really.
The Beatles did some awfully self-indulgent stuff that sounds horribly dated today but they completely altered the face of music -- this thread doesn't exist without them. I don't really think they can be overrated though some of their tunes might be.
There's a side of me that says the Rolling Stones are overrated but I think the songs themselves are great -- I've always just thought their albums were poorly produced -- Keith's guitar in the mix is so often way too low and to me they've sometimes sounded like a Mick Jagger solo project instead of a band.
