Oh so now they were cheating the artist? Oh really? Then tell me sir how is it that the labels agreed to Apple's terms? That's not cheating artists. I certainly hope that you don't make any mistakes in your life and correct them and hope that people will forgive and move on. Because according to you, you deserve no amount of praise for correcting a mistake.
I said I was "glad they changed their minds." But I don't think one needs tons of praise for doing the right thing.
Still, this wasn't about the big record labels. It was about small artists who would have their music distributed for free when they're struggling to make a name for themselves among trendy artists with big billing. These smaller artists have no bargaining power and would have had to submit to Apple's terms or not have their music distributed.
