Groove 2 for iOS acts as a digital DJ, creating playlists based on your listening history.
Groove 2 is difficult to describe in a nutshell: it’s like Calibre for music, while also serving as a cross between Apple’s Genius tool and iTunes.
While Genius makes listening suggestions based on songs you’ve rated, Groove goes one step further and acts as your personal DJ. The app tracks your listening habits and uses this information to create custom playlists it thinks you’ll enjoy. As well as spinning some digital decks, the app can download missing artwork, album information, artist bios and song tags, helping you organize your music library.
The feature that makes Groove really special is its smart playlists. With a single tap, the app will create a playlist from your music based on what you’ve listened to in the past, or based on certain tags. Mashable journalist Alan Henry had the following verdict: “When I tested the app, I was surprised at how well Groove was able to match up songs that I had listened to or lost in the depths of my music library.” You can also create “Surprise Me” playlists, which are similar to the iPod and iPhone’s “shuffle” feature and chooses different songs from your library every time.
The app recognizes smart gestures so you can change tracks, control the volume and create new playlists while driving, without having to take your eyes off the road. It works with Apple TV and AirPlay-enabled speakers, and you can also share music with friends and family via Facebook or Twitter.
Groove 2 downloads all song and artist information from Last.fm, and the app also scrobbles tracks you listen to back to the music website, so you can keep track of what you’ve heard online as well.
Groove 2 works on iPhone, iPod and iPad and is available from the iTunes Store for $1.99.
