I use musicbrainz, but be careful. It doesn't get all the tracks correct, so make sure they are the right one before you let it correct the ID3 tag.
D3 Editor hardly does any more than Itunes. And it cant edit filenames and folders.
TriTag also did not seem to offer any more features, and can't even edit albumart.
Musorg however, does seem like the beginning of somthing good.
Musorg lets you
-search through your music finder-style
-rename files and directories
and the interface looks good!
It does lack many importent features that im used to from tag&rename. Shame its so unfinished, I shall keep an eye on it though.
Thanks for the tip guys!
Edit: seems Musorg does not have an album edit feature after all. Too bad. Heres hoping it gets better.
I am new to Mac, how did you get it to work?
I tried a few mac programs and wasn't happy with them.
I also like EAC/LAME for ripping CD's.
