One of Google Music's aim-squarely-at-Apple features is 'Scan and Match', which does what it says on the tin. Just like Apple's £22-a-year iTunes Match, it scans your music library and matches it with Google's own library, giving you instant streaming access for free. Well, now it's meant to be working, and what's more, it apparently scans any music you've already uploaded to Google too.
I can't say I've noticed it working for my tracks, but then I have most of my music uploaded already, so Google's probably working its magic server-side. Anyway, now it's officially rolled out in the US as well, which means it should be working here too. One up for Google, and if you're on and iPhone, you can still grab it, either through the browser or an app like GoMusic. Got to love free stuff, especially at this rather-expensive time of the year.
