Operator Please are an Aussie band that're doing quite well for themselves at the moment.
I'm pretty sure the whole band is actually under 18.
It's some really good Pop-rock, and after loading up Audiosurf for the first time and trying to think of which song to play, "Leave It Alone" was the first thing that came to mind. I haven't even been listening to them much, I just thought about the crescendos in the song, and the chorus... and the fact that it's one of 'those' songs where, at one point, the singer says "Stop!" and everyone stops for a beat or so. When that happens, and the game pretty much stops completely for a second or two... it just made me smile.
I've been showing this game to everyone since I got it, and this is the song I've been making them play.
