Got MM 3.1 a few weeks ago, it tags and manages my 10'000+ songs far better than iTunes ! Morevoer it syncs smoothly with iPod.

I have MM 3.0. I think Media Monkey is your worst nightmare. It will not only blows away all of your album art work (it can’t see art work stored in the iTunes database), but in my case it replaced all the albums with “David Holt: Reel & Rock” and my 22000+ songs–gone. Backup your library before playing with this and whatever you do DON’T PAY FOR IT!!

This is one of very few apps that supports internationalization - if you have bunch of non-english music.
Highly recommend

DON'T SPANK THIS MONKEY!!
i also am highly impressed with this small, very powerful application. The interface is very simple to use and will get your music library in order THE WAY YOU WANT IT!, Sure to give the other big name players a run for it... and without the ads and constant barrage of requests for personal info. Oh, did i mention that it's free? GOOOD MONKEY!

This is seriously the best mp3 organizer/player I've ever come across, and it's FREE! I've been looking for something like this forever that had exactly these features, and this is by far the best one I've come across. Amazing...

One word: WOW!
Since it's free, I was expecting a half-assed jukebox with tons of ads. Far from it--it's similar to Media Jukebox / Real Player but a bit more streamlined and with a few really useful tools (e.g. renamer).

I'm truly impressed
