Spotify isn't made by Apple or Google. It doesn't have any allegiances to this device or that platform. That means that all the program has to worry about is creating the best music experience possible. Spotify can sync your mp3s to your iPod, and if you have a smartphone it'll work with that, too, whether its an iPhone or an Android or a Windows Phone or a Symbian. You won't ever have to worry about losing access to your music because you change devices or operating system. Spotify works for music-- plain and simple.
