Apple Launches iTunes 10.5.1 With iTunes Match

Apple has finally released iTunes Match with the iTunes 10.5.1 update. iTunes Match allows users to download or stream their music anywhere, on any device. For $24.99 per year, Apple will make all your music available in the cloud, even if it wasn't downloaded from iTunes. Your music will play at 256 Kbps, regardless of the quality of your copy.

It's not a bad deal, and it's available now through iTunes 10.5.1. Fire up Software Update from the Apple menu on your Mac, or Programs file on Windows to get the latest update.
