I did a search for File tagging, but the threads are ~5 years old, and some of the software is no longer available, or not really what I'm looking for.

I have around 80Gigs of Music. ~10Gigs of completely correct MP3 Tags. ~20 Gigs of Foreign Music most tag editors won't recognize, and ~10Gigs of Mixtapes, and stuff that isn't produced by major lables.

Do any of you have an extremely good program for auto tagging the library? I won't mind paying a small fee as long as the software is worth it. I just don't want to spend months of my free time manually tagging this library.

Note: I have googled some stuff, but their free trials are junk, and most of the reviews seem biased.
