So,Im listening tospotify on my PC to the StaredPlaylist. I have about 100 songs and like 7 hours of listening and one moment I go on the Internet and when Im about to  go to change the song i have 500 songs and 30 hours of listening?!?!Im really confused I didn't add any songs to my stared or anything and not on myspotify phone app either. The weird thing is they were added on the same time exactly.

did it just say that, or did the songs actually appear in your playlist as well?

The song was actually there like you could see them and if you click on it, it plays like a regular song. I thought maybe a mistake or sone thing so I logged off and went back on but it was still there...
