Watching the Super Bowl? Then You May Need Shazam.

Shazam is the mobile app that identifies songs by “listening” to the track in question and then querying a database.  When it works–which is most of the time–it’s actually kind of magical.  In fact, it works so well that it’s the fourth-most popular iOS app ever.

So what does this have to do with the Giants-Patriots game on Sunday?  From Evolver.fm:

Fans will be able to tag the music played by Interscope artists at the halftime show for access to exclusive add-on content, and to find out more about the artists who are performing including on Facebook and Twitter, but that’s just the music-oriented tip of the iceberg. Brands of all kinds plan to give away more than one million items to viewers who tag stuff — everything from two Toyota Camrys to the opportunity to donate a dollar to charity — and approximately one half of the ads appearing during the show will be Shazam-enabled.

Cool, huh?  Too bad that because of all kinds of stupid rules we Canadians won’t get to see most of those ads.
