Google Music

With the roll out of Google Music in Europe we saw Google include the scan and match feature that offers up a quick scanning of your library and then instantly makes the tracks available in the cloud much like how iTunes Match works. At the time, Google made no efforts to divulge when that feature would see other regions. Now though, they've gone ahead and made it available in the US as per their announcement on Google+:

Traveling this season and want to make sure your music goes with you? Add up to 20,000 songs from your music collection to Google Play and stream it to your Android devices and your computer, anywhere you go.

Our new music matching feature gets your songs into your online music library on Google Play much faster. We’ll scan your collection and quickly rebuild it in the cloud - all for free. And we’ll stream your music back to you at up to 320 kbps.

This feature is live today for people in the US, following our European launch last month. Check it out: http://goo.gl/Hehq6!  It’ll be music to your ears.

The advantage for Google here is the fact that they've kept it free and it's automatic. As a Google Music customer, you're likely to not even notice it happening as it's all pretty much done in the background. It's a pretty slick feature that a lot of people are sure to love. Say goodbye to uploading your whole music library!
