Thought I'd throw in my thoughts.
I'll come right out and say this. I have onyl known Muse from about 3 years the first year and a half was only knowing KoC from GHII, the next year was having litterly only SMBH, KoC, Assassin, MotP, Hysteria, and SS in my "little repetoir". For the past six months however, I became a completely devoted fan to the point that my friends call me obsessed. As soon as I saw the original Wembley gigs, I pointed at Matt and said "I want to do that." Its what inspired me to get into playing piano seriously and eventually getting a guitar. Now, if Matt's gonna wus out from playing piano, hes gonna stop more kids, like me, from being inspired to take on the instrument.
I saw them for the first time back in October, at the PruCenter. And luckily for me, they played CE for the first time in the US since 2007(?). And honestly, I dont believe I deserved it. Going to my first ever Muse gig and getting CE, while hundreds of other US fans have gone to 3 or 4 gigs and still came out empty handed. But it made me realize why I love Muse so much. You go in expecting the generic, and they melt your face off. Sure the tickets where a bit pricey at $70, but every seat in the arena was the best seat in the house. And even without CE it would have been well worth it. Thats why I honestly dont care where Muse goes next. They can make a MJ tribute album and I'll still love them to death (that may be a bit of a stretch.. but still...)
EDIT: For their next tour, the one thing I'd like, is longer setlists and less cheese. I mean come on, give the longest Muse setlist in history to Asia? And doing 23 songs two nights in a row at Wembley this Sept proves they still got it in them. So for the next tour, a setlsit with about 6 new songs, 7 from the 2006-2009 era, 5 from 2001-2005 and 2 from 1999-2000 woudl make me quite happy. New fans like the new stuff, old fans like the old stuff. True fans, like everything.
