I actually don't really like any music to be described as crap.
Just because some people don't like it doesn't make it crap, there is all sorts of music and all sorts of tastes in music and there is plenty of room for all. I also don't really like the whole trying to split music in genres and people saying "I don't like X genre of music" as there tends to be good and bad in all of them (I don't like most drum and bass, but goldies timeless is a great album)
(I make an exception for Rebecca Black, Friday.... that is crap)
