It’s disgusting. You can only hear music that you purchased on your iPod in the new app.. This is blatantly unfair. I can’t download the purchases on my iPad Pro. In the beginning I didn’t know about the change. I purchased all kinds of wires, thinking I could download it from my HP laptop. I have over 2000 dollars worth of songs. The only solution is I have to go to the store and look for the song then I can play it. I don’t remember half of what I purchased. Not to mention the songs I down load from CD’s onto my HP and download onto my iPod. In the words of the song, it’s “ all about money ain’t a dam thing funny, got to have a con in the land of milk and honey”. We’ve been had.
