I'll check those on the list. Any other recommendations in the meantime or feedback on what's listed so far?
I've used mediamonkey for several years. I keep everything in one directory with 80 gigs of mp3 organized by Artist/Album/Track. It will let you pull in files from different directories scattered hither and yon but I prefer to have them all together. I have a temporary directory where I rip to and then check the tags before I move the files to my regular music directory. I only use Mediamonkey to organize the directory. I use CDex to rip cd's, which does a good job of tagging, and mp3tagtools to tag anything I don't use CDex to rip. I have some tracks I have used audacity to make from albums and tapes but most of the collection is cd's ripped using CDex. Mediamonky and mp3tagtools are both freebies. You'll probably like mp3gain also. It will normalize an entire directory so they all play at the same volume. CDex does this too but sometimes I decide to change the level after the cd has been ripped.
