Unable To Play Songs From My Playlists On My Tablet

[Yusimi]

"Spotify is now free on mobile and tablet!  It's time to play everywhere for free!  On mobile, you can listen to artists, albums and playlists in shuffle mode.  On tablet, you can play any song you want, any time you like."

I downloaded the Spotify app. from the Google PlayStore to my .Dell Streak 7 TABLET (Android 2.2.2).  Per the above quoted advertisement, I should be able to listen to any of the songs in my playlists, but instead I get a message that I can only listen to radio.  

Solutions are welcome.

Unfortunately android version 2.2 can't run the up to date version of spotify which is required for the new free service. If you could update to android 2.3 then you would be able to download the current app version and enjoy free spotify.
