Artists on songs are wrong.
I'm having a very annoying issue in my music library. For instance, there's a song called Kamikaze by KB & Prisca and now it shows KB & Prisca on the majority of KB's songs where it should just say KB. It's not just with that artist. There are a few others as well. This is only happening on my iPhone 6. They show up the way the should on my iPod Classic and on my MacBook Pro.
