I like quite a lot of music, except for the super commercial (like cheap dance hits). This varies from metal to classical. I like to say: For every mood there is a kind of music.I have a slight preference for "alternative" music, although alternative is mainstream these days.
I do not believe that there are people that are good in everything. My respect goes out to revolutionary self-made people who can think for themselves.
