What are these red circle symbols that suddenly appear in my iTunes library on my iPhone?
I just upgraded to iOS7 and iTunes 11.1 and now my music library on my iPhone has these weird synmbols next to certain songs, red circles with little red squares, and I'm unable to play them now. They play on my MacBook Pro but won't play on my iPhone 4. I've tried looking online but a little frustrated not knowing where to look. Googling "red circle with red square" hasn't been very helpful.
