I can't put my sister's music onto my iPod touch
I have a 3rd generation iPod touch, and my sister has a Nano. In the iTunes library on our computer (it's not a Mac), all of our music is in the Purchased playlist. However, I also have a "Purchased on MY iPod" playlist. That has all the music on my iPod. For some reason, iTunes won't let me take her music from the Purchased playist and put it onto my iPod's playlist. I don't know what's going on. There isn't even a sync button on iTunes, anymore, from what I can see. I don't know what to do because that means, if I can't get her music, she can't get mine, and I bought a lot of music for her on my iPod because hers was missing for a while and we just shared mine (sorry, that's not really relevent). If we can't sync, she doesn't get the songs that are technically hers.
