Guvera is a new online music service that is set to launch in the United States on March 30, 2010. Based out of Australia, the start-up company looks to change how we pay for music by offering downloadable MP3s free of charge.

How is this possible? Basically, Guvera leverages consumer data with advertisers. I will wait and see what Guvera is all about on March 30, but I have to say that I am not a big fan of companies that use my personal info as some sort of currency with advertisers. So until March 30, I am going to be kicking it old-school with a healthy mix of iTunes and Pandora.
