I like Marilyn Manson even when I'm not on drugs, at least up to Mechanical Animals. I kind of stopped paying attention after that one.
For some reason I love the Presidents of the USA. I don't like much other general rock and roll type music, but their stuff is just fun. Their lyrics are often quite corny and they always do silly things in their live shows.
I don't listen to much techno and classical, but I usually like it when I do listen.
outside of metal i like classic rock like Kansas, Boston, Foreigner, journey, Styx, Queen etc. but i still have a place in my heart for funk and 70's horn bands like Tower of Power, Chicago
