Why do some songs songs randomly get removed from your playlists?


AC Question

I have added hundreds of songs to several playlists over time. At some point, some of the songs will just disappear from my playlist and I either have to re-add it or find an alternative to add back.

My problem is that I am trying to locate songs I have added that have been removed so I can either "re-add" or find alternative versions.

Can anyone speak to this?

I am merely using google play on internet explorer while at work.
