Do you have cell connection at those places?
10$ per month for access to every song, album, artist, etc.... on any device. You of course would only have access to new music when you had a wifi or cell connection.
In addition to the unlimited access to music, the user experience for sharing, updating playlists, etc, and radio is far superior to iTunes or anything else that I know of. Spotify is badass if you are a music lover!
