All, I have a couple of problems with Spotify Premium that seem to be common on different phones.

I load a playlist from my PC over wifi, set spotify to off-line after tracks have transferred to the phone, I am unable to play, getting the message, "can't play this playlist!  This playlist is not available while in offline mode".   

So, if I set Spotify to on-line then after a few seconds I can now play music on my Nokia .  I noticed my data usage is staggeringly high due to spotify, but if I turn off my phone network connection, then no more music.  I would have thought off-line playing implied no network connection needed?  

I am guessing the points above are related.

This is very poor performance and suggests the software is not working properly.   

I will remove the software and reinstall, maybe that will make a difference.  

Would appreciate any help on this, thx - c
