But don't you think Good Charlotte atleast would prefer their music to sound good instead of suck?
I think the desire to perform well always is there to a certain degree.
Yes but that doesn't change the fact that they don't put any effort into making it sound good.

Although I love punk rock, playing the same note over and over is NOT art.

If I collect lots of horse *, put it on a red vacuum cleaner and take pictures of it,
you will most likely think the pictures suck, but they are nevertheless art.
If the creator can find some sort of deapth behind doing that than yes it is art. Just not good art. When a little kid draws a picture of his or her family, that is art. It jsut is really bad art. However, when some teenager draws an anime picture because they like anime, it is more than likely not going to be art. It's the same with music. Ive composed some short things that I consider to be art. Just, really really BAD art. However, writing shallow pop songs is not art.
