Lost my favorite songs from my playlists

[vickyyy]

Hello everybody 🙂

I have been using Spotify for about a year and this summer I decided to get Premium. Since I got it I noticed that I lost some songs (like about 20) from my playlists and two of them are my favorite. I searched the songs on Spotify to see if they were still there but I didn't find anything. I asked a friend who has Spotify (but not Premium) to search the songs and she found them all! I don't understand and I don't know what to do.

I'm sad that I'm not able to listen to my favorite songs. Please help me 😞

Thank you
