Give it up pals. Go to netlabels. Share your music at full quality avoiding getting stuck with some corporate media giant. Share your music with creative commons licences. By supporting netlabels you're empowering the scene, the musicians, the users. Not some brand_name_corporation.
If your music is gonna be floating on the net, it better be at full quality, exactly as you want it, with your credits clearly shown in the file's metadata.
My 2cents.
