i recently got my iPhone 7+ two weeks ago and I love it but today I'm having problem with my music app. I synced my own music from iTunes to my iPhone last night and today when I'm listening to my songs, I notice half of my songs skips to the middle of the song or it just ends very early. I tried closing the music app and opening it again, some of the songs that were affected were back to normal but some of them still skips to the middle or ends early. I don't know what to do :/ I had no problem with any of my songs on my iPod nano. I don't know if it's a bug in the app or just my songs corrupted?
