My saved songs have disappeared and been replaced by random songs

[Bella16]

Hi There

All my saved songs have disappeared. When I go in to 'your music' and songs, there is now random songs there that I did not save or listen too. I have deleted the app and re-installed twice, but it is still the same situation. Does anyone have any other suggestions on how to get my saved songs back and get rid of what is there?

Thanks so much
