Music recognition, a service that allows wireless subscribers to identify music wherever it is heard, is now available in the United States.

Musicphone, a San Francisco-based technology company, has partnered with U.K.-based Shazam Entertainment to provide U.S. consumers with the latter's music recognition service.

The Musicphone service, called MusicID, is launching with AT&T Wireless subscribers. By dialing #43 on their handsets, the service combs through an extensive music catalog and returns results to the handset in seconds via text message. The service, which is billed through the wireless carrier and includes text messaging fees, costs $1 per use.

Shazam already has more than 1 million users across Europe, Asia and Oceania. In the United Kingdom alone, consumers have purchased about 3 million tracks through the service, according to the company.

Musicphone plans to extend MusicID to other U.S. carriers; it is preparing for a launch with Virgin Mobile USA. Musicphone says it will eventually integrate music recognition into other mobile services such as ringtones, dedications and song downloads.

"What's great about MusicID is that it introduces a 'search factor' to existing music services. A subscriber can now quickly find the ringtone or the download version of a particular song he or she likes by dialing three digits on his or her phone," says Birame Sock, CEO/founder of Musicphone.
