the riders give suggestions to the editors alot of the time. if the editor tries it out and sees it doesnt work he picks a song that does work and runs it by the rider. if the rider likes it, they use it in a segment.
if riders would get to choose 96% of all segments would prob be rap.. i let the riders decide, or more like suggest songs. usualy i go with the ones they choose. But when one of them wanted Britney Spears in his part i had to say no.
