lost music

[user-removed]

I can't log in with Facebook and logged in with my email, but all my songs except two are gone. All my list all albums and artist. I logged off Facebook, Uninstaller the app and still unable to long in. I also checked to see if I accidentally erased and the results said no everything is good. What can I do to log in with facebook. Omg, at leat a few hundred songs lost, but Shazam still shoes I have songs on Spotify.
