I suppose it's my opinion.
GnR not relevant, never heard a good word about their shows in recent years
AM maybe relevant in the fact they've recently released a record that got to number 1 but everyone quickly realised it was terrible and as a live band they don't have that spark anymore. A lot of their older fans now bored like myself.
Elton I would argue has always been relevant, appeals to all generations and I'm looking forward to seeing him.
Sam Smith only relevant recently due to media attention and a song that gained popularity through tiktok but it's widely agreed that he's fell off everyone's radar musically.
QOTSA beyond boring.
Prodigy maybe not relevant for the new generation but their music stands the test of time and they've still got more energy in their sets after all these years than all the above.
I've said my piece but there's so many more artists who could've smashed it this year.
