Description Michiel 2006-11-30 13:34:07 UTC 
Version:            (using KDE KDE 3.5.2)
Installed from:    Ubuntu Packages
OS:                Linux

Maybe I misunderstand the meaning of 'synchronize'.

I have previously used Amarok but went back to windows (for reasons unrelated to Amarok, it is stil a kickass audio player). Now I have installed Ubuntu. Installed Amarok.

Connected my ipod, and it was properly recognised. I went into the settings to 'configure media device' and saw the 'synchronize' option. I checked it. Fiddled around for a bit, rated some songs, and then synced with the ipod. Disconnected the ipod, success! My ratings had propagated.
Then I went to one of my rating-based playlists and everything was gone.
Why? Because Amarok has just wiped out all existing ratings.

I suggest that if you find a rating on the ipod and no rating exists on Amarok you should probably set the Amarok rating to the ipod one, not remove the ipod rating.

I spent a lot of time rating those songs so I am a little ticked off.
