Oh man. Spend a day with Nightwish? I can't even imagine. Just being in their presence would be amazing enough for me. O_O But lets see. I might go hiking with Tuomas. I'd go shopping with Anette! ^.^ Go get coffee and make fun of people with Emppu. Hehe. I'd ask Marco when his band is going on tour and get him to sign a CD for me, then drink some beer. Even though I don't like beer, with Marco, it'd be the drink of the gods. lol. And with Jukka, hm. Maybe I'd just babysit his kids? Wait, they probably don't speak English... that would be difficult. Um. He can come drink with me and Marco! XD

To spend a day with my favorite band....wow to be honest i doubt i would remember it...we would all be so drunk off your asses to even remember what happened..lolll btw the band is Amon Amarth. despite the fact that they could probably drink my ass under the table...doesn't mean...it wouldn't be a hellavu lotta fun xD

i like any rock bands but if i had to pick someone i would pick Josh Groban. He sings like an angel. He and i would go get some coffee, talk about anything that we like to do in our spare time. Go to the island here by texas walk on the beach and just enjoy our company.

I used to work at SeaWorld, and I think it'd be awesome to take Green Day there for a day; see all the shows, go on a backstage tour and ride the roller coasters. Hell, their kids and wives can come too. I'd probably be too busy tripping over Billie's feet all day to seem remotely intelligent, but I'd try to have some intelligent conversations and generally try to show my appreciation for their music and all it's done for me.

First I would squeal with happiness. :D

Then I would take Nick Cave out for a nice lunch.

I have more than one favorite band:

-Taking Back Sunday
-My Chemical Romance
-Green Day

Honestly? I'd probably just order some pizza and play video games with them all day. And of course I'd probably force them to give me an interview/interrogation.
Or going to cause havoc in the local mall. xD
And eventually... They'd probably end up getting raped and/or lock up in my closet never to escape. xD (Not really, I'm not a horrible person... Okay maybe the rape part is true, but I can't help it, they're all so smexy)

if i got to spend a day with my favorit band i would probaly want to go back to thier place and freak out over every little thing they own, i would probaly only be there for a few mintes before they call edsecurity and got me draged out of there

I would spend the day with linkin Park........I probably would start out with hyproventalating and once i calm down just do some fun stuff like discuss the best topic ever! MUSIC and what inspired them to write what they wrote and then go to the amusement park or something and hang/play video games

o.o I.... think they're still alive... prolly just wanna listen to them play live =3 >> << or ask if they'd play for my wedding...

Me and Iggy Pop hehe that would kick a$$. what would we do? i have no idea but it would be fun

[ I'd be with CN BLUE, definitly. ]

I'd wanna go somewhere... away from people. x D
It'd be no fun with them being drooled all over by mad fangirls such as myself. >__>
*gigglesnort*
Yuss. I'd wanna be the only one. x D; <3

On a more serious note; I'd probably just ask them to play for me. v.v;
Other than that I don't know what I'd do...
...Do whatever they wanted, I guess. <3

...Or, stuff you'd do on a date. Yah, that'd be good too. ; 3

probably sing some tunes
=/

i like j-pop

I'd have to hang with All Time Low, and we'd probably all play Pokemon and make bad penis jokes.

Well:
If I was spending the day with Kanye West I would go for a romantic meal with him before showing him the way to my bedroom.
If I was with Queen I would want to have a private concert, just them and me in the O2 Arena :D
If I was with P!NK I would want to go out for a major party and get very drunk.
It just really depends on who I am with :P
