iPhone Won't Sync Music
My iPhone 4 refuses to sync music.
I have it set to Sync Only Checked Items, and to Sync at 128 kbps. It's worked perfectly fine in the past, but for some reason, recently it's only synced a few of the new songs on my machine. It won't get through the alphabet at all before it declares Mission Accomplished - something that's very annoying, considering the new Sufjan EP has not made it onto my iPhone despite numerous attempts.
The last time I synced, it just two songs from the "B's." I just updated to 4.1, but the problem has existed since well before the update.
What could I be doing wrong?
