They weren’t originally on the lineup in 2021, though. They were a late addition so people wouldn’t have been able to get day tickets for them etc. They’re still able to shift upwards of 100,000 tickets on tour in their sleep. Whilst I agree, I doubt they’d be one of the first names suggested when booking headliners, I think they’re an outright headliner still. They will flit between Download, R&L & IOW every few years forever, I think.
Also I agree twitch Victorious being a major - 65k is really big.
