I have been ripping vinyl for a while. after I have bounced the audio files to aifs I usually put them in i-tunes, get the keys in mixed in key, add in the key in the comments of i-tunes, and put in the bpms. Then I put the files in an external drive, which I use for Serato.

Today, I did the same as usual, ripped some new records, went through all the usual steps, but this time, none of the info will stay on the files, nothing except the song title shows up, and the songs are really slow to load when just using serato to listen without being connected to the box. When they do load the info drops out, even if I've put the info back in manually, when the track loads the info drops out. Really infuriating to be honest.

Funny enough, I upgraded i-tunes today, so I feel that is the problem, as usual apple takes a good version of the program and messes it up.

Any idea what the problem could be?
