#1, first and foremost, my biggest complaint that revolves around music is big-venue tickets. Now my issue(s) are multiple and I'll try and touch on all of them.
A) Ticketmaster. Why is this organization/company allowed to retain a true monopoly on almost all big venue events. It's not just concerts, but sporting events, social 'rallys', etc. If it's a big venue, chances are ticketmaster has their name on the ticket. We, the consumer, have next to no choice in how we purchase our tickets. It's either from Ticketmaster directly, from a 2nd/3rd party 'broker', who originally got their tickets from TM or directly from a consumer, who got their tickets via TM. Or, we can go buy our tickets from the less-than-optimal scalper, who if you followed the purchase chain, it's the same as above... it all leads back to TM.
2) TicketMaster Fees. Why is TM allowed to charge multiple "fees" as well as "surcharges". Prime example. Last year I bought 4 tickets to a concert. The tickets were $35 each. My total bill was $190. Wait, wuh? Someone help me with this math. 35x4 (or 35+35+35+35) = $140. WTF is with the extra $50? Well, there was a $4 TM Fee (can't remember the name of that charge anymore) per ticket as well as an $8.50 per ticket "handling fee". Actually I think there was some tax on top of it now that I think about it, so it was actually over $200 for $140 worth of concert tickets. FML.
So on top of gripe #1 being that TM holds a monoply on our concerts, they ALSO are allowed to charge bullshit fees on top of it all. And the fees don't seem to be the same from one concert to the next. When Eric Clapton came to town a few yrs ago (and I think the same was with McCartney a couple yrs back), the per-ticket fees were at least $15 per ticket.
