Playing synced music on the Iphone

[Kai_m]

I do have an Iphone 5, all software is updated and I do have a Premium account..

For some of the playlists I use the offline mode and synced the songs on to the Iphone. However some tracks I cant listen to. It lloks like the track wont start playing  at all.

Hello!

Are the tracks greyed out or do you get any message when you try and click on them?
