If she wants to protect the little people in the music industry, she should offer to allow Apple to use her music royalty-free for six months if they pay new artists during the three month free period.
A pathetically naive solution. Who gets to pick who is "little" and "new"? What if you're a just a bit bigger than "little" and just a bit older than "new"? Tough luck, you get to help multi-millionaire company Apple build a new business for themselves, at no recompense.
There is always a problem when people try to draw an artificial line, where the rules totally change, in the middle of a market. Because there is always someone who falls on just the wrong side of the line that gets hammered, while someone else, practically identical, on the other side of the line reaps the benefits.
Without sharing the risk of the free trial.
Why should she feel obliged to share any risk with Apple? It's not her business venture. She's doing just fine without it.
