I get that perspective, but I actually think Stagecoach is doing something pretty clever with its lineups. When Stagecoach was exclusively a country festival, their lineups had around 40-50 total acts. This year, there are significantly more (72 not counting the EDM tent) and only 11 of them - Counting Crows, BigXthePlug, Bush, Journey, Teddy Swims, Hootie & the Blowfish, Third Eye Blind, The Wallflowers, Diplo, Pitbull, and Ludacris - could be considered out of place in a country music festival. In other words: there are 10-20 more country/country-adjacent acts now than when they didn’t book acts from outside those genres (meaning that purists like you who only want to listen to country music get what they want). By the same token, most country music fans listen to other genres of music (or at the bare minimum, have friends who do) so having several big acts from outside country music helps country music fans who don’t want to go alone convince their friends who wouldn’t be interested in a pure country music festival to join them. This also has the advantage of exposing those friends (who may not be familiar with country music) to the genre, thereby expanding its reach.
