Mucis keeps buffering/ glitching

[WolfieBlack]

I have had spotify for a couple of months and downloaded practically all my music onto it and it worked perfectly fine. Now it's started to buffer and glitch whenever a song gets to around a minuet.

I made sure it was nothing to do with my device by restarting it, trying it with earphones and switching from spotify from youtube and it only happens on spotify.

I even tried deleting the app and re-installing, logging out then in again but nothings worked.

Please help?
