Album artwork is incorrect on Iphone 6s
Ever since i purchased my iphone6s everything has been working great! However over the past few weeks my music has started acting up a little bit. All the songs I have downloaded play perfectly fine, however, when I add them to my phone the album artwork is completely wrong. For example - I would add a song by Drake to my phone, and it would attach album artwork from Mac Miller. I've tried deleting and re-adding the music but it just picks a different album cover each time. All the artwork is completely fine in my iTunes as well.
Any help would be amazing!
iPhone 6s, iOS 9.2.1
