Album: Pandemonium!

There are many B2K songs that could've made this list, but "What a Girl Wants" takes the cake. Not because it's funny to think about a group of male 20-year-olds expounding on what exactly a girl wants and need, but because of what happens three minutes into the song: These dudes try to get their Lenny Williams on and talk on the track about their astrological sign.

If they really knew what a girl needs and wants, they would know that a girl wants a guy with some bass in his voice who they can't share jeans with. But, hey, what do we know? —Damien Scott
