Although many record companies in the United States refused to issue CD singles, they readily issued DVD singles, and some popular DVD singles include Kelly Clarkson's "A Moment Like This", Jessica Simpson's "With You", Beyoncé's "Crazy in Love", Christina Aguilera’s "Fighter", Britney Spears’s "Toxic" and Iron Maiden's "Satellite 15... The Final Frontier". According to the RIAA, a music video single is defined as 1-2 songs per video OR under 15 minutes running time.
