Hi Guys,

please please help me. A few days ago I found a song in the charts which was so great and I immediately saved it in my own playlist. 

I was playing that song a few days and since today the song disappeared suddenly and I dont find it anymore!! How is that possible?? All the other songs are still there!!!! God **bleep** I need that song back but I dont know the title and the Singer. 

Please Guys....help me

I dont need help to find the title. Just if it is possible to reset my playlist to how it was before for example.

If you have a computer or laptop, download Spotify on it. Log in on your account and look at the listen history

Didnt help. I just get shown the Playlists which I played and not the Song.
