iPhone or iPod touch only: The already-good Pandora music recommendation engine app for the iPhone has gotten better with version 2.0, which adds Cover Flow view, artist and song info, and bookmark previews. Take a look at some screenshots.
You'll need to sign into your free Pandora account to get started and see your stations. Make a new recommendation-driven station based on an artist; check out the suggest-as-you-tap search drop-down.
Once a song starts playing, you can give it the thumbs up or thumbs down (which informs Pandora's future recommendations), or tap the up arrow to get more options, like...
The ability to bookmark the song or artist, or buy the track from iTunes.
Turn your device to get into Cover Flow view, which works just like native iTunes (though I noticed a little flickering in the background album covers in my test).
Tap on the top right button to get artist details (shown here) and song details (shown below).
When you're wondering why Pandora threw a recommendation into your playlist, the song info will tell you why. The Pandora 2.0 app is a free download for the iPhone or iPod touch only.
