Pretty much answer those questions, don't say what bands you like and who you don't like. That's not the point, it can be very hard to define music. A lot of people would say serialism isn't music, yet others would (I do). Others would say the work done by John Cage isn't music. People say Justin Bieber is music, and yes just because his voice is to high to be 16 and that he mostly likely doesn't make any of his songs, it is music, although painful to say. It all really comes down to personal opinion.
I have my own opinions, but I have to go to school so DISCUSS!
I just want to say, thank you msuic for always being there for me when no one else was.
