Music & digital media: moral standing on music sharing

I have no qualms with sharing music online. I feel like all music should be available to everyone for free no matter what and money for the artist should be made through concerts and exhibitions. I feel this way because buying music is much too expensive, I would stream all of my music before I would buy any of it. I find pandora to be an extremely useful music resource because I listen to music that I would have never discovered without it.
