How do I retain just the music I own?

[jontyrees]

I had a Windows phone from the first week the Samsung Focus came out, had two Lumia 920s, a 1520, and most recently a 640. I liked the OS, but finally grew tired of not being able to do some things, the poor Facebook app, etc, etc. My 640 is still in excellent condition though, and I would like to put it to use as a full time jukebox, and available mini-tablet (it's running Windows Phone 8.1 Update 2). Here's my question - how do I clean up the MSFT Music app so that I see ONLY my own music that I downloaded to the phone? I have ditched the MSFT Music subscription, but all the music from there that I had pulled to the phone still shows up, and it seems like the phone won't play anything, maybe even the songs I actually owned.

Has anyone else had this problem and found a solution?

Thanks!
