Music-recognition service Shazam has launched a subscription-based mobile and online music service, the Ultimate Music Discovery Engine.

The service extends the company's existing mobile offering by adding online features and mobile-phone shopping. In essence the service lets users identify any music they are interested in simply by dialling a number (2580) on their mobile phone and pointing it at any loud sound source.

Intelligent software then matches the fingerprint of the audio to a 3.5-million track database, despatching the results to the end user by SMS. You don't need to register to use the service, but it costs 50p for a successful identification (plus network charges). If you are a registered user, your tags are filed on a page you can access online.

The service also offers subscribers a way to buy associated products - CDs, ringtones, downloads and more - using their mobile phone. Shazam is working with Amazon, Ticketmaster, iTunes and Kelkoo to provide this service.

Andrew Fisher, CEO of Shazam, said: "We enable users to not only identify and purchase music when and where they hear it, but also allow them to access a broader selection of material related to the track - with the choice of precisely which format they want to receive it in.''

Two subscription tariffs are available: £3 per month lets users tag unlimited songs when they're out and about; for £4.50 per month they can tag songs while also receiving two additional products, either ringtones or full track downloads.
