The latest company looking to take a bite out of Shazam’s music recognition business is TuneUp Media. It’s previously best known for its desktop TuneUp software, which fixes metadata, removes duplicate songs and pulls in other content for people’s desktop music collections. The new iPhone app essentially presents Shazam’s core features: identifying a song that’s playing, providing audio clips and iTunes purchasing links, pulling in lyrics, and letting users share to Facebook and Twitter. It’s free, and uses Gracenote’s music recognition technology to do the identifying. And the business model? That remains somewhat unclear.
