The Recording Industry Association of America, the company that deals with single certifications (gold, platinum, diamond), announced earlier today that it will be including on-demand audio and video streams to its certification program. In light of this new change, Lady Gaga’s “Bad Romance” has been officially certified DIAMOND for selling over 10,000,000 copies in the United States alone. This makes the song Gaga’s most successful in the US as well as one of the only Diamond-certified songs of the 21st century.
