* A beta version of iTunes Match became available last night, and while only developers can currently get at it, the limited software release sheds more light on what the service will be like once it officially rolls out this fall. For the $25 annual fee, music can be streamed and/or downloaded from iTunes Match onto any iPhone, iPad, iPod Touch, or Mac computer. Songs in users' collections that are already available on iTunes won't need to be uploaded -- they'll be streamed from Apple's master copy. Check out this video preview, courtesy of Insanely Great Mac, of how it all works. (MacRumors and Insanely Great Mac)
