I mean, let's be fair, you're not going to undersell it, are you?
"Oh, it's a bang-average lineup this year, lads, we've just only got one of the greatest bands to ever come out of Sheffield topping the bill as well as a former Glastonbury headliner and, for some reason, that bunch of blokes from Rotherham pretending to be about a decade-and-a-half younger than they are."
I can't even disagree that this doesnt look likely. Eminem in the same year again though I guess it's been 8 years. Add BMTH to that and Bicep playing the Chevron makes sense. I'm not though as a fan of Eminem, QOTSA also gets you there but then none of those do lol.
He might not have heard all 6 headliners.
