How long will spotify work without an internet connection?

[MusicMomma]

HI there, 

I am about to set off on a 2 month row across the Atlantic Ocean. I won't have internet access for the entirety of this journey. I want to know whether or not spotify app will allow me to continue to play my offline playlists even if the app hasn't connected to the internet in over a month? 
Cheers,

Sean

Unfortunately, you have to go online every 30 days or your downloaded music will become unplayable.

I'm not sure if they would be able or willing to work some magic on your account but this seems like an excellent opportunity for some good PR so I suggest you get in touch with them direct here.

Good luck with the trip!
