1 item could not be synced. See iTunes for more information.
"See iTunes...." .... WHERE? I have looked all over the mess-interface that is iTunes 12.1 now.
HELP!

I tried many different methods from the internet, including here.
Nothing worked except to go, one by one, through the list of 5,000 songs, looking for the ⚠ and then locating the files on my disk (nowhere unusual, exactly where they were supposed to be, along with other songs on the same album which were not problems).
Ugh. Apple really should provide an automated way to do this.
