Apple has announced that iTunes 10.5.1 beta 2 has been issued to developers and that iTunes Match is now available for testing on Apple TV.

Apple said the new beta build of iTunes includes a number of important stability and performance improvements.

Apple was reportedly to publicly release its iTunes Match service by the end of last month. iTunes Match stores users' music library in iCloud and enables the use of the library from anywhere and at any time on devices such as the iPhone, iPad, iPod touch, computer and now Apple TV.

Apple Insider has reported that people involved in the beta test have said that the iTunes Match service still has a number of problems like stalling and incorrect matching that need to be resolved. It is uncertain whether those issues were taken care of in the new iTunes beta.

iTunes 10.5.1 beta 1 was sent to developers in October after iTunes 10.5 went public. Apple released an iOS 5.0.1 beta on Wednesday, which it said is meant to take care of a battery life problem on iOS 5 devices.

iTunes Match will cost $24.99 a year when it becomes available.
