I suppose such discussions would be better placed in the "Movies and Music" forum (seriously, it needs renaming...) because this isn't about original creative content so much as opinion.
Also, the 'VS threads' rules apply: if you're going to say one or the other, you must explain why to avoid spamming.
For my part, I'm going to say that music is art, so the question itself may need to be better defined :P
I agree with Strop, Music is art, and art could be music. Both are a way to express yourself... Why not show us some of your work if you have made any?
Music is art, art is something you express emotions through, music is one way to do that. So is painting, drawing, singing, writing, things like that. They are all art and they all are things that you can express feelings through.
