Spotify offers just about everything you love about the desktop client, with some added goodies for audiophiles. It's a solid enough app to make users who don't already use the service think about downloading it. Since it's the only way to access Spotify's millions of songs on your mobile gadget, it's a must-have app for Spotify subscribers.
The app, just like the desktop service, gives you unlimited listening to streaming radio of more than 15 million songs if you are a Premium subscriber (If you're not a Premium subscriber, all you can do is look but not listen). That kicks off the ads that play between songs and lets you download songs to your gadget, too. Spotify on your mobile gadget is a spitting image of Spotify on your desktop. It has a similar layout and the same great audio quality you know and love. There are some added features like gapless playback and crossfading that work really well on mobile gadgets, too. The app even lets you track what your friends listen to if you're signed in through Facebook. The app lacks advanced widgets and only includes the standard 4x1 banner player, though. Outside of that, there's nothing the desktop version can do that this app can't.
If you're already a big fan of Spotify, you absolutely need this app. It works as well as the desktop app and lets you take your music on the go.
