Apple has made a beta version of its new iTunes Match cloud music service available to developers. The service, announced in June, allows users to pay $25 a year for the ability to match songs on their personal library with songs in the iTunes Store library—and upload any songs that can’t be matched—for cloud access from any Mac or iOS device. The service limits the total number of songs at 25,000, and iTunes Store purchases do not count against that total.

In the email announcing the beta release, Apple states that beta subscribers will receive an additional three months free with their paid 12 month subscription, and advises users to maintain a local backup of their iTunes library, as well as any music they upload to iCloud. “Apple will periodically reset your iCloud library during the beta and it is critical that you backup your music regularly,” the email states. “Some features and optimizations of iTunes Match will not be available during the beta.” In support of the service, Apple has released iTunes 10.5 beta 6.1, which is now available to registered developers from the iOS Dev Center.
Insanely Great Mac has posted a video walkthrough of the new service showing that it is capable of not only allowing for downloads to iOS devices—which is how the company’s current “iTunes in the Cloud” service works—but also streaming, integrating the customer’s iTunes Match library into the Music application, and letting the user choose between downloading or streaming each song. Apple is expected to officially launch iTunes Match later this fall. [via Mac Rumors]
Update: Apple has posted a notice on the iTunes Match signup page noting that “beta testing has begun with an initial set of developers.
