The line-up definitely skews toward people in their 30s and 40s, not teens and 20s. Same as Food & Wine. I imagine the same reason--a demographic that has the money to get blitzed on $8 beers and $10 margaritas but can handle it and not puke in the bushes.
That said, Toby Keith is as close to icon status as it gets in country music these days, and missing member or not, Fifth Harmony is a top pop act.
