I'm into most things except recycled swamp donkey music such as pop music, new metal and all this punk stuff for skater kids so they can learn about girls. Good soul and jazz is great, dance music particularly drum'n'bass and breakbeat (not really into 4 to the floor), old skool metal (which we now call hard rock thanks to modern metal crap) like Maiden, Metallica etc. Also classical greats like Holst and Prokofiev.
Most music is rubbish.
Most people listen to recycled crap because they're happy to be entertained by the same old thing.
It's a myth that it's just as easy to be innovative today as it was 40 years a go. We're running out of melodies. Maybe that's why all this new metal/punk is just chords and no melody? Or is it cos these kids can't play their instruments these days?
Edit: Ahh, forgot to mention I hate music that has a rebelious, self loathing or pointlessly depressive undertone to it. Like "I hate america" or "I lead a lonely life". Kids need to get through their self pitying rebelious stage of their adolesense ASAP and get jobs!
