i propose a new idea…
what about a popular band like dave matthews, pearl jam, cold play, green day, etc…
one of them did a concert tour where the set lists for every show on the tour are voted on by fans with tickets to the show
so like fans vote online, the night before the show voting closes… they can pick from a pool (hopefully all of the bands songs) their fav songs and vote for them. then the top 15-20 voted on songs by the fans is what they play at the show
for the fans concert tour. the first concert where the fans decide the set list
btw if this ever does become a reality i would like some tickets 😀
