oh hell no...haha. I'm definitely using MP3 Tag Studio. It's fast, but still slow going when you have this much music. I'm also running into files with bad tags every once and a while that i have to strip and fix which slows things down. The most time consuming part is just looking up all the years and labels in allmusic.com and interpunk.com, and fixing any mis-spellings or punctuations that existed before. The rest goes pretty quick. I do a v1->v2 copy, mass clean up to remove v1, then mass set year, genre, and label in the comment field.
