So just who is on the bill? Tunesmith Adam Levine and Maroon 5 will be on stage, along with "Happy" singer Pharrell Williams, Kylie Minogue and even Blondie. Speaking of nostalgia, Chrissie Hynde and Robert Plant are also scheduled to perform. There is speculation that this year's festival will mark the launch of iTunes Radio or Beats Music in the U.K. Both streaming services debuted in the U.S. While Apple is still awaiting the closing of its deal to purchase Beats Audio, nothing prevents it from expanding Beats Music to other countries.
Apple has held the event every year starting in 2007. So far, more than 430 acts have been presented on stage.
