I tried Tag & Rename. I bought Tag and Rename. Now I can't stand it.

My favourite tagger (BY FAR) is Dr.Tag. Here are the programs I have used extensively:

MP3 Tag Studio (this used to be my primary. Could not handle multiple files across multiple folders when I used to use it)
iTunes
Tag and Rename
ID3TagIt! (It was free and I thought a lot better than Tag & Rename for editing multiple files at one time over different folders)
Dr.Tag - don't know when the last update came out, but this program just fit like a glove. Haven't done any tagging in about a year though, so I hope any new version didn't ruin what used to be a really good program.
