Hi. Are you following the instructions here to synch the music to your mobile? Do you get any error messages while the playlists synch?
Do the tracks actually show up in your playlist on your mobile? Are they greyed out? What happens if you try to play one of them?
When you synch the playlit to you mobile, does it show the tracks are downloading? Do you het the grey download icon against each track and does it turn green?
