Well, I'll give you that. If you use scripts, particularly custom scripts, MP3Tag is irreplaceable.
I stopped using these when I stopped bothering to organize my music collection's layout. This happened when I switched to using iTunes and had it set to keep the media folder organized.. At first I was very reluctant to let iTunes (or any other algorithm) touch my collection. Actually, I preferred not using iTunes at all since I was used to far superior music players like MusicBee and Foobar.
But iTunes is so well-integrated into OS X, and 3rd party music players are so low on features, that I just decided to give up and stick with iTunes. It's working pretty well surprisingly.
I let iTunes keep my music library folder organized also. I use MP3Tag to sort my albums, once matched using iTunes Match, to a backup location for archiving.
