Do you have a ton of music that your afraid of losing if your PC ends up busted? Music libraries these days can become huge, and a ton of work to maintain. I recently started using Google Music, which lets you upload all your music up to 20,000 songs. They keep it safe for you and give you access to it so you can stream it to any computer with an internet connection or you can stream to your smartphone. They are still working out the kinks but I enjoy it so far. The interface is intuitive enough so that even those with computer phobia can easily get through the menus. I see this easily competing with ITunes within the next few years and I can totally see Google Music being offered as a feature in a car stereo system much like Pandora is now.
Keep your eyes on it….
