i would recommend doubletwist.com
Works just like iTunes for your droid. It copys your pre-existing iTunes library as well as playlists that you can then copy to your phone easily
The thing that I have bee looking for is a package that will offer easy Backup/Restore capibilities. This is something that iTunes offers which actually helps the Jailbroken community.
question... I use iTunes, but iTunes DOES NOT control my music I have all my music in folders and I would have NO PROBLEM having another program import my music from my folders. is there some thing I'm missing about iTunes?
