“On November 14, 2011 (a few weeks later than promised), Apple released iTunes Match, a $25-a-year, cloud-based service designed to provide access to your iTunes music library from a computer, iOS device, or Apple TV,” Kirk McElhearn writes for Macworld.

“The idea is simple: iTunes scans your music library, sends the information about your songs to Apple’s servers, and then either ‘matches’ music that’s in both your library and the iTunes Store, or uploads the music that isn’t in the iTunes Store,” McElhearn writes. “Then, you can either download or stream (depending on the hardware) all of your music from a Mac or PC running iTunes 10; an iPhone, iPad, or iPod touch running iOS 5 or later; or a second- or third-generation Apple TV.”

McElhearn writes, “In theory, iTunes Match is a great idea. In practice, however, everything doesn’t work as well as it should in the realm of iTunes Match, with users facing a number of hiccups and difficulties since the service’s inception. With renewal notices going out to those who signed up early on, it will be interesting to see how many people pony up for another year.”
