My favourite music got replaced!

[Haxxel]

Recently Discover Weekly made a list comprised of only latino music (something that I never listens to).

And now I found that all my saved music was replaced with latino music! And a playlist with the same music was added.

Maybe my account has been hacked? So I have changed my password and logged out everywhere. Hopefully the problem is gone now.

But ALL MY SONGS! All of them is gone, I have saved songs for ages and listens to them all the time. How can i get them back?! Can my account be reset?

The playlists remain but not the favourite songs.
