Bruno Mars Revenge
Bruno Mars joined Katy Perry and Lady Gaga with his own branded version of Tap Tap Revenge from Disney Mobile. The smartphone rhythm game features 10 tracks to play along with, including hits "Grenade" and "Just The Way You Are," as well as his new release "The Lazy Song." Additional features include album-inspired game themes, a photo gallery, artist bio and the ability to access Mars' Twitter feed and a fan chat room. The app costs $5 and is thus far limited to the iPhone.

Music Hunter

We Are Hunted introduced a new music discovery app for the iPad called Music Hunter. The app lets users browse through a list of recommended songs after first entering their preferred genre and mood. The Echo Nest provides the recommendation engine, and U.K. digital music service 7digital allows users to stream song samples of each. It also includes one-click links to purchase from iTunes, and sharing track information on Twitter and Facebook.

Pitchify
A mashup of music blogs Pitchfork and Drowned in Sound, integrated with European music streaming service Spotify. The site identifies any song with an average rating or better from the two blogs and then streams them through a Spotify feed. Obviously the Spotify integration only works in Europe, but U.S. users can still see which songs/albums are getting the best reviews and then sample them elsewhere. It also includes links back to the respective sites for those who want to read the reviews, and updates can be sent via RSS feeds or Twitter.

8Tracks/Topspin
Playslist/radio service 8Tracks struck a deal with Topspin that will direct fans to buy music from artists' websites. The "buy" link on songs played via 8Tracks now will lead users to artists Topspin-powered store, where they can buy not only the track, but also merchandise, concert tickets, product bundles, etc. And since users can embed their 8Tracks playlist virtually anywhere online, the buy link goes where the playlist goes. Other digital services using Topspins widgets include Songkick, Pitchfork, Spin and Stereogum.

Shazam
Music ID service Shazam introduced a pair of new promotions this week. First, it launched a new "Golden Ticket" initiative designed to let artists reward fans who use the app to tag their songs. The first participating artist, Selena Gomez, will let fans opt to enter a sweepstakes to see her in concert if they use the app to tag her new single "Who Says." Shazam tells Billboard that it expects to do several more such promotions with additional artists in the coming weeks and months. Additionally, Shazam is giving all users of the Android Shazam app unlimited tagging for the rest of the year. The first three months of this promotion is being sponsored by eBay. Presumably other sponsors will sign on to underwrite the additional months.
