You’ve probably been hearing a lot about Google Music lately, but there are still those who aren’t really sure about what it is or how exactly it can push everybody’s music experience a notch higher. If you’re one of those people still scratching their heads, then this article is for you.

Simply put, Google Music is a cloud-based service that enables you to store up to 20,000 songs for in an online locker, which can be made accessible both online and offline from your desktop, your tablet, or your smartphone. You can easily add audio collections from your hard drive, iTunes and Windows Media Player directly to Google Music, and even purchase songs from its Android Market-based store. Currently, the service has tracks from Universal Music, Sony and EMI, as well as from other independent labels, so you’re sure to have a wide array of genres to choose from. As long as you have a relatively fast internet connection, you’ll be able to stream your music without any hassle.

What’s great about Google Music is that it’s all for free – a definite advantage when compared to Apple’s locker fee of $25 a year for 25,000 songs. Users will also be treated to a free downloadable track every few days or so, which is a great way to test the service, as well as to promote music.
