Oasis have lost the plot, Noels song writing talent has dried up, he openly adminted copying a "Soundtrack Of Our Lives" song for Lyla, and I've heard them back to back and theres nothing between them, when you're doing that shit you've had your time, yes they were great once, but that was when they made great songs.
Muse is an ideal choice, you said "they've been around for 10 years, what were they doing for the first 8?" I think you'll find they came on the scene in around 00/01 so thats the best part of 7 years, take into acount 3 years for writing and finding a sound that works and gelling as a band and it all ads up, just casue you and all your mates down the pub wear rose tinted shades and think its still 1995 doesnt mean Muse are shit, seeing as you obviously dont know how long they've been around you wont know how good they are live and how highly rated their show is, I'm not even a massive fan, but some of their tunes are awesome and they deserve the respect they get, having a new band in their prime open wembley is a great idea, getting some washed up has beens isnt
