What's better than free music? Lots of stuff, probably -- but it's still on the top of our list. Rdio is hoping to get you hooked into its vowel-agnostic music streaming ways with the promise of "up to six months of free music" without ads or credit card numbers. The deal adds a number of countries to the list (of which the US is already a member) -- including the UK, Australia, Canada, France and Spain. There are 15 in total (again, already including the US). Germany and Brazil are sadly still excluded from the free music party. While the offering is ad-free, each month does include a limited number of plays (though Rdio's not giving an exact number at the moment), which will count down on your page. More info on the offering can be found after the break.
