After a recent update all my songs and albums in 'your music have disappeared. I spent ages adding them all when you removed the library feature which was buggy in its own right! And now they have all been removed from my mobile device again. The artists section is only one that has anything listed other than 'discover', but this only shows artists I have followed with 0 tracks from each.
How do I get all my music back so that it is accessible in one place so I can shuffle through it on my mobile???

I am also having an issue with downloading offline playlists. When I select new playlists as offline on my mobile they seem to display a grey offline icon (circular down arrow) but never seem to download correctly or be available when the phone is not online.

Any help with these issues would be appreciated, cause I love using spotify but it's really frustrating when everything breaks after each update you release.

Thanks,
Steve
