Pink Floyd produced one great album: Dark Side of the Moon. And that album was largely great for two songs: Eclipse and Brain Damage (and those ARE fantastic songs). However, Pink Floyd's influence on music is greatly overstated; bands like Yes and David Bowie had a far bigger impact. That, combined with the legions of Pink Floyd fans who find it blasphemous to dislike Floyd or have different musical tastes, and the band gets quickly becomes quite annoying.
