OK, I use Tritag for making my mp3s have nice tags, but it doesn’t have either lyric finding or artwork finding. “Mactags.blogspot.com”:http://mactags.blogspot.com if you can believe it actually has a review of all Mac based MP3 taggers (talk about narrowcasting).
Here are some good recommendations:
“MP3-Info”:http://mactags.blogspot.com/2007/02/important-mp3-renamer-i-forgot-to.html. This lets you right click and look at tags, which is OK.
“MP3 ID3X”://http://www.three-2-one.com/321apps/main/global/index1.htm It isn’t freeware, but costs $18 and is ancient (not updated since 2005), on the other hand, it is the only mac tool I can find that does artwork and lyric finding. I have been using pearlyrics for lyric finding and it is just so, so.
