Spotify
Like the recently released Pandora for Android, Spotify is a music streaming service. But it is significantly different compared to Pandora in some important areas. First, it’s not just a smart radio service, it allows you to pick and play from an enormous catalog of songs. Second, it offers offline sync so that you can listen to your music even when you don’t have a cellular or WiFi signal. It’s basically a massive music library right at your fingertips. You will need a Spotify premium subscription to use this application. You can run Spotify in the background on your G1 while you browse the web or run other applications.
Offline syncing is quick and the app clearly shows progress status as the sync is happening. Spotify also syncs with the desktop application – anything you do on the desktop app will be reflected surprisingly quickly on the G1 itself. You can drag songs into the mobile folder on the desktop app to move songs to your smartphone. The interface is very clean and the tabbed player gets out of the way to let you play with other controls even as a song is playing. Playlist management is intuitive and powerful. Overall, this is a great new music streaming app for the G1.
