Well, lets look at this with Fezzy glasses for just a second. If we're operating under the usual assumption that I will be experiencing these things severely inebriated, Dudefest seems infinitely more awful than it already was. While Branson would likely be a significantly less stressful experience. Definitely Branson.
Why would Dudefest be worse while drunk? Even if you don't like the music, you probably would if intoxicated. I've found myself liking songs like "Call Me Maybe", "Sexy and I Know It", "Tik Tok" and "Gangnam Style" while drunk for example.
Then you're not a very good music elitist.
Plus, there is that real life meme that people don't change when they are drunk. Violent drunks are always violent, they just hide it better when they are sober, that kind of thing. Maybe you really like bad music and you just hide that (even from yourself) out of embarrassment when you're sober?
