I registered Tag&Rename and don't use it anymore... A week after I started using it I found ID3TagIt which had much better support for multi-tag editing. The first tagger I tried was Tag Studio. But it chopped off the "/##" track# text portions from my 6000 tracks. Ugh. I haven't seen any toold to put that data back yet (automatically by checking how many files are in each folder or just letting me enter a # per group of files).

I just found Dr.Tag this past week and so far this seems like it's the best fit for what I consider a clean and VERY useful MP3 tagging interface. I have yet to use it for a large number of edits though. I like its presentation for multi-tagging though (similar to what I previously said was good about iTunes). Just wary about registering it to soon. I'm also evaluating the new version of Tag&Rename (I have a licence so why not)
