For whatever it's worth, I came to this forum looking for a solution to the same problem. I have a single Last.fm account, and realized recently that MB wasn't syncing all of my plays. I tested out the similar script in Media Monkey, with much better results. Music Bee tells me out of 6155 tracks, I have 9 tracks that have been played 4 times. Media Monkey tells me I have 83 tracks that have been played 4 times. For some reason Music Bee has problems recording play counts for tracks that have been played multiple times. Although I like the MB interface, tagging options, and auto-playlist functions (without paid upgrades) much better than Media Monkey, I think Media Monkey is going to have to win for the play count syncing, which is the only thing I miss from the iTunes ecosystem. I'm using a HTC Incredible 2 with Simple Last.fm Scrobbler.
