I had the same issue as yourself and have had pretty good results from mp3tag which I think that I learned about on this forum. I don't think that it queries AMG due to subscription costs but I live in hope that at some point PerfectTUNES will offer this functionality instead!

Certainly mp3tag is free, easy to use and worth at least a try.

Cheers,

Tony.
