Google has updated the Music Manager for its cloud-based music service. While you could previously use the manager to upload as many as 20,000 songs to Google Music or to download tracks you’d purchased from the service — now you can use it to download the songs you’ve uploaded.
In other words, you can use Google Music to backup your music library, stream it to any computer with a web browser or to your Android phone or tablet, and download your music to a PC.
So you can create a backup of your music collection using Google Music and re-download it if your hard drive crashes, you laptop is stolen, or you buy a new PC.
Unfortunately there’s no easy way to download just a few songs at a time using the music manager. What happens when you click the “Download my library” button is that Google asks you what folder you’d like to store your music in, and then is starts to download all of your songs.
But you can download individual tracks or albums from the Google Music website.
