Apple released iTunes 10.5.1 on Monday, an update that includes the long-awaited launch of iTunes Match. There are no other feature changes announced in the patch notes.
iTunes Match Introductory Offer
iTunes Match is Apple’s $24.99 per year service that matches all the music in your music library to songs on the company’s iCloud servers and then makes those songs available to all of your iTunes-enabled devices and computers. Similar to what the company already offers for iTunes purchases, iTunes Match will match songs gotten from other music download services, CDs, and even pirated material, assuming it can find a match.
You can download the update from Apple’s iTunes download page. The company is also listing it on its main Support > Downloads page, but as of this writing, the iTunes 10.5.1 for Mac and iTunes 10.5.1 for Windows (64 bit) articles both now link to version 10.5.1, and the update is also showing up in Software Update on OS X and the Apple Updater in Windows.
