I would pay top money to see these artists. Me and my Dad paid $90 per person for U2360 in Miami (first U2 show & best concert ever!) and I would definitely pay anything to see U2 again.
A) Rush
My parents saw them when they came here in 2008, I chickened out. I regret it, since I really like their music much more than I did back then.
B) The Rolling Stones
Same scenario as Rush - parents saw them when they came here, chickened out - regret it. For me, highly unlikely they'll go back on the road again.
C) Paul McCartney
Came here last year, problem was it was on a Monday, so couldn't go. Hopefully he'll be on the road in the next few years.
D) Coldplay
I wouldn't pay the highest price, but I would love to see them live. Music has grown on me over the past few years.
E) Pink Floyd / Roger Waters
We were invited to fly to Fort Lauderdale to see Roger Waters' The Wall last year, but we couldn't. Would have loved to see the show live.
F) Madonna
Yeah, I have shitty musical tastes, but it's the result of your parents being fans.
Now that I saw U2 live, I can "partially" die (they were at the top of my bucket list) but I have a strong desire of seeing the artists above as well, plus a few others.
