As successful as 'Guardians of the Galaxy' was at the box-office (and, as the highest-grossing film of the year, it certainly was that), the film's iconic soundtrack was equally as successful. "Awesome Mix Vol. 1" spent two weeks at No. 1 on the Billboard 200 chart and is currently the 10th largest selling album of 2014. You've been able to buy the digital album, the CD, vinyl and even a "Deluxe Edition," but so far, no actual cassette like the mix tape in the film. But, that's all about to change.
