The most prevalent problem I’ve had in recent years is a constant lack of hard drive space for my music library. I have a 75 gb library and I feel like I’m always running out of space. iTunes Match, released in November from Apple, has finally helped me alleviate this.
The idea is this: Apple has a bunch of music on it’s servers and we have a bunch of music on our computers. A lot of that music matches. So there’s no reason to have to upload all of our music to Apple when they have it already. iTunes Match scans your library, matches all it can, and uploads the rest. You can then choose to remove the physical files from your computer, remove the ones you rarely listen to, etc. You can re-download or stream it whenever you want from your computer, iPhone, iPod Touch, iPad, or Apple TV. iTunes Match is $25 a year.
