Digital music: iPod 4G compatibility with Musicmatch 10

iPod 4G compatibility with Musicmatch 10

Hi,

I just got a 4G 20gb Ipod photo as a gift. I have a pretty large collection (25 gb or so) of mp3's from p2p networks, friends, CD's and vinyl, etc. and some of it is pretty jumbled in terms of the tags or duplicates. I've played around with iTunes, but it doesn't really supply tags or check for duplicates. Before I load up my iPod, I was hoping to find an easier way to clean up the files and was looking at MMJB 10+ for the supertagging and duplicate sort features. However, Musicmatch's site basically tells you that it doesn't support the iPod (it's not on the compatible devices lists). Is there any way to use MMJB 10+ as my default for the music manager for iPod? Alternatively, is there some software where I could just clean up the mp3 files on my hard drive before importing to iTunes?

Thanks in advance.
