Can't put a price on memories.
I had to buy a second-hand ticket that was double its retail value to see Bjork ($150 general admission). I paid $150 for a mid-venue seat to see Antony Hegarty, who isn't a concert artist in the slightest. Both of those shows were seven hours away so I had to pay for traveling accommodations to boot. I paid $700 for a VIP package to see Madge last year. I saw Janet twice, both times were near $200. And if Janet comes back around I'm dropping whatever it takes to get front row.
