In preparation for a cross-country airplane ride, I loaded up spotify on my ipod touch with music from my library and put together a bunch of offline playlists.  "This is going to be a GREAT 6-hour flight," I thought.

Then I turned off my ipod when they said "all electronic devices must be turned off".

Then when we were in the air, I turned it back on and set it to airplane mode.

When I opened spotify, it asked me to log in.  Then it said "Turn Off Airplane Mode or Use Wi-Fi to Access Data".

Then when I did that, it said something about no DNS server available.  

Then, 6 hours of fidgety boredom in silence.

If I want to listen to spotify on a plane, does it mean that I can't shut down the ipod when they tell us to shut off our electronic devices?  How am I supposed to listen to my offline music when I'm -- wait for it -- OFFLINE??
