What is the best Media Manager for use with Sansa Fuze

Well, one of the benefits of Rhapsody is Dynamic Playlists.  You can define criteria, then set the playlist to auto-refresh every time you connect.  

Sample: Select 100 Songs of Rating >= 3 and Genre != Podcast and Genre != Audiobook

Also, Rhapsody syncs the Ratings of songs you have in your Library.  If you go through a lot of music, you can make great use of Ratings.  I keep a Dynamic Playlist of songs that need ratings…

Sample: Select 100 Songs of Rating = Not Rated and Genre != Podcast and Genre != Audiobook
