Two weeks ago Beats Electronics dropped a World Cup commercial featuring some of the biggest athletes on earth. It was a rollicking display of star power, and seemed at several points to make sly reference to the companys recent union with Apple. Today Beats Music, the streaming service owned by the same company, is turning up the volume on this campaign, releasing a remix of Jungle with a rap cameo by Jay-Z and making this new track available exclusively on Beats Music for the next week. Beats Music is significantly smaller than its competitors in the streaming-music industry.
