I recently discovered that I had google music on my cellphone (HTC sensation). Now, since I own an iPod (4-5 years old), I didn’t get that much utility out of it. But, I can see how it can come in handy. Since you can store up to 20,000 songs online, Google music can serve as an online backup for your mp3’s lest your hard drive fail (you also have the ability to download any uploaded music at anytime). Any music that you have uploaded can be streamed to your cellphone anywhere you have a data (4G/3G) connection. I’m just curious to see if anyone has gotten any additional mileage from this that I may be missing out on.
