the wrong song is playing

[emilyschmidt2]

So I was going through my music on Spotify trying to delete some old songs, I was under the "songs" section. some of my music is playing completely different songs. for example when I was sampling one of my songs it was playing something from Bridget Mendler and I do not have any of her music. I tried re-downloading the app, I tried deleting the song and re-adding it but nothing will work. also I don't have premium so I can't actually play the song to see if it's playing the wrong thing. please help. btw I'm on my iPhone 6s.
