Apple-owned Beats Music has launched a US contest to promote itself and next month's iTunes Festival in London. The #GoWithMe promotion offers 25 winners a chance to take a friend to see one of five concerts. Options include Kiesza, Calvin Harris, Pharrell Williams/Jungle, Maroon 5/Matthew Koma, or Ed Sheeran/Foy Vance.
Each winner will get two plane tickets to London and two nights' hotel accommodations. Participants must have a Beats Music account, although they don't have to be paying subscribers.
