Synchronize and manage music collections in your iTunes and WMP.

From James Willis:

"MusicBridge allows people who use both iTunes and WMP on the same machine to keep their libraries in sync. MusicBridge offers a variety of synchronization options so that you can manage your music collection in either media player or both.MusicBridge duplicates meta-data between Windows Media Player and iTunes, it does not copy physical files between the applications."

*Added note: Will transfer ratings, album art, play count, playlists, and all tag data to and from iTunes and WMP. Works with iTunes 9 and WMP 12.
