New Years Tunes

OK, so I'm trying to pick a music theme for our "used to be small and is now outgrowing our house" New Years Eve party. I'm thinking 90's one hit wonders. And not just because I can buy the ITunes Essentials list off of ITunes. I mean, who doesn't want to listen to Hansen on New Years? Or do y'all think I should go classy and actually play some "cocktail" music?

Thoughts? Ideas? Input? If you were a 30/40 something with kids at a New Years party guaranteed to break up by 9pm, what would you want to listen to???
