An even bigger fact here is that the musical landscape is changing.
How many new great guitar led rock bands have emerged in the last 10 years? Rock and roll isn't dead, it never will be and it will go full circle and have its time again i am sure.
In the same way pop will never die and is in a huge resurgence these days.
I do agree with you that some people seem to feel entitled to see huge rock bands headlining festivals. This leads to the same headliners on a three year cycle which in itself becomes tedious.
I think its time to embrace a wider range of headliners or simply don't buy tickets and go and see Arena tours and stadium shows of your favorite acts at around £150 a ticket.
I'm a metal head but i tell you what - some of the best acts I've seen in recent years are pure pop.
We’ve always tried to get as close as possible to the front of the other stage. Further back and it does get souless., folk passing through, food outlets, groups of folk chatting etc are distractions, much worse than all the other main stages.
