I used I-Tunes to put all the songs in the right folders then uninstalled it. I use MediaMonkey to keep up tags and sort my collection. I have the paid version and like it a lot. Only problem is, like so many other programs is the memory leak that happens when you use it for five or six hours. Sometime as much as 50 to 75k. So I use foobar 2000 to play songs. Around 7 to 10k without any plugins. You know, whatever works.
Still looking for that perfect player/Organizer.
