I think they've just been a bit unlucky with the competition. For example having the likes Arctic Monkeys and Gorillaz above them at werchter.
With headliners lacking now, who wants to see Pearl Jam or Metallica for the 100th time.
I wouldn't bet against QOTSA headlining Werchter next year. Especially with there commitments for the 2024 cancellations.
What is we have it all wrong and Muse are being offered the spot that Foo Fighters could have had at Glastonbury. I think I saw somewhere that muse are being offered the spots foo fighters were meant to have at the European Festivals. It would be a killer tho because i will somehow have to get into Glasto
