At the moment my favorite artists are Tool, Jimmi Hendrix, Muse, Phace and Mistantrop, and the Prodigy, though generally my favourite genres are neurofunk and breakcore. I like most genres that aren't classified as "pop music". Not that I'm the type of "anti-mainstream" person that dislikes things because they're popular, I find it hard to image though for people to not want to drive their head trough a wall when hearing someone like Rihanna sing on the radio.
