but they're not stealing the music. The music belongs to the artist.
In MOST cases somebody originally bought the cd. In ALL cases it's not stealing, it's sharing. Look at it like this:
Somebody paints a picture. Someone takes a picture of it and puts it online. Someone takes that picture and uses it as an avatar or even just downloads a jpg onto their desktop. It's NOT stealing.
It's also no different than downloading a song onto your desktop.
I don't know what your avatar is, bonovox, but by your definition you are probably stealing it. You should find the original, buy it, take a picture of it, and THEN put it online.
