[saltyjuan]

So out of curosity me and my friend were comparing our spotify.me and I was very shocked to see it say under "Favorite artist- Fall out Boy' and I have never listened to this band and then it says my favorite genres are pop punk/post grunge/pop rock. Very confused and if your wondering here is my playist and comparing to these genres I am just??????
