iPhone doesn't sync all music?
 

As everyone and their mother is no doubt aware by now, I got a new iPhone over the weekend. I left it plugged into my laptop last night to sync my music, which iTunes says is about 15 GB. When I woke this morning, it had finished syncing but only transferred about 11 GB.

I thought at first that it must be because I checked the option to convert higher bitrate songs to 128 kbps first, but the numbers of tracks don't add up - there should be around 3300 tracks but my phone only shows 2979 songs.

Is there a way to figure out which songs didn't sync? I quickly scrolled through the playlists in question and didn't see any of those little exclamation point-missing file errors.

Thanks!
