That's not the same. The price to get into, for example, a Drake concert is determined not by Drake, but by how much people are willing to pay to see Drake.

If the total cost, including all fees and taxes, is more then you want to pay, then don't buy tickets.

Don't blame Ticketmaster for the high price to see Drake in concert, blame Drake fans!

But if the Drake concert is cancelled, or re-scheduled, then do a chargeback.
