That's what I did, and when I powered it up on the new computer, the library was exactly how I left it on my old computer. That wasn't the issue, the issue was that in the interim, I synced my phone to my old desktop, so that computer got an updated library as well. Complicating matters was that my phone was experiencing a serious lack of storage, prompting me to remove some of the downloads from my phone. When synced, this kind of messed up my purchased playlist, and for some reason the play count on some of the new items had been reset. So, I decided to just reset everything. Now however, my purchased playlist appears to be locked, as when I right-click a song and choose add to playlist, Purchased is not one of the items listed. Could you help me figure out why that would be and help me fix that?
