From what I understand though, this is actually more about people not purchasing albums anymore, so now artists have to basically make the bulk of their money from concerts.
Ticketmaster doesn’t force dynamic pricing for instance; that’s a choice the artist has made in order to maximise their profit from the ticket sales.
I don’t know if the tickets need to be quite as expensive as they are, for artists to make a profit - likely not. But they certainly are making a lot less money from the likes of Spotify than they used to make from albums sales, so it has to be a big part of the problem.
People like Oasis take the piss to be honest, because I doubt they’ve actually run out of money (according to this YouTube channel that was talking about them, they seem to think the brothers both still have plenty of 90s money, I dunno how you check this stuff… but yeah. Makes sense that they shouldn’t have spent it all unless they were really fucking stupid with their investments or lack thereof). So they really don’t need to be making this much money from the ticket sales, but for newer bands the Spotify thing should apply.
