I've used it quite a bit and have manually profiled over 1100 songs. The only reason I use it is becuase I have a large collection (120 gigs) of MP3's that have no tags that are completely useless on the empeg. MoodLogic has to ability to identify the song and retrieve the tag info for it. Unfortunatly, it only does Artist and Track name right now but the folks at MoodLogic have said that in future release, more info will be available.
