When you open Google Play Music's site, you'll see this message: "Encore! Encore! Now you can upload up to 50,000 of your favorite songs and listen to them on your phone or on the web."

To upload music, you can use the Chrome app or Music Manager for Windows/Mac/Linux. Google only uploads songs if they can't be found in the Play Music database, which has more 30 million songs. Otherwise, Google uses the high-quality version from its own database and doesn't waste bandwidth to upload your music files.
