Q: Exclamation points on every song on my iPhone but the ones I've just added

Did you ever find an answer?  I am having the EXACT same problem.

Same exact thing for me. Songs just started disappearing from the iPhone. When I plugged in and looked at the list of music that was supposed to be on the iPhone, they're listed but have a grey exclamation point next to them. I tried manually syncing to no avail. Nothing worked except "deleting" the song from the iPhone (through iTunes) then re-adding. What's going on, Apple?

The songs in my iTunes library (on my MacBook) work just fine, and the songs were definitely playable on the iPhone until they just up and disappeared.

Same exact thing happened to me last night. Does anybody know a solution?

the music got moved from its original location

The thing is my computer has the music and it is playable, but it won't sync to my iPhone. It has all of my music in the folder labeled music under iPhone but when i try to play them they can't... just the exclamation point.

1. Connect your iPhone to iTunes
2. Select your iPhone under Devices
3. Click on the Music tab
4. Uncheck the box next to Sync Music
5. Sync your phone
   1. This will delete all the music off of your phone
6. Re-check the box next to Sync Music
7. Sync your phone

This should re-sync all your music to your phone and solve your problem.
