I like to listen to stuff that meets the basic criteria of music. It must have a rhythm and changing tones, in other words: melody.
Not everything that is called music actually contains a melody. I've noticed certain types of dubstep to be a particularly notorious offenders.
Yes, but ars gratia artis. I dunno, I'm not keen on dubstep, but I think if someone creates it as art then it is art. Semantics over what we call music I guess. Maybe acoustic art would be a better term for some things.
