You know what I love? A fun rap song. “Just a Friend” by Biz Markie? Absolutely. “Get Ur Freak On” by Missy Elliott? Twice, please. Or three times. And don’t get me started on “Lip Gloss,” because I will never, ever stop.

And you know what I love even more? A fun rap song with a sung chorus. “Let Me Blow Ya Mind?” One of the few times I will seek out Gwen Stefani. “Mo Money, Mo Problems?” Possibly the best thing that happened in 1997.

Some people dismiss this pop-rap as lightweight and lame, but what-ever. Sometimes, it’s nice just to dance and not worry about the political ramifications. I mean, if you groove to “Low,” are you saying it’s a good idea to bend your dance partner so low to the ground that she looks like “a pornography poster?” Or, if you’re a woman, that you want to resemble said poster in front of a roomful of sweaty strangers?

Don’t get me wrong: There are plenty of dirty rap songs that I like. They just don’t put me in a good mood. I can never escape the feeling that I’m belittling myself and my friends every time I bob my head.

But “Boyfriend/Girlfriend,” by C-Side featuring Keyshia Cole, makes me happy in an uncomplicated way. See the video after the jump.

Seriously, how fun is this song? The beat is catchy, and it has just the right tempo for dancing in your car. You can sway from side to side without moving so fast that you could accidentally hit the gas and slam into somebody.

I also love what a throwback it is. It has the sunniness and humor that make “Now That We Found Love,” by Heavy D and the Boyz, and “I Got a Man,” by Positive K, so much crazy fun.

Those upbeat qualities are certainly in “Boyfriend/Girlfriend’s” lyrics. These guys have such massive crushes on their girlfriends that they put them in the Top 8 on their MySpace pages. They love their ladies so much that they take them on shopping sprees at the mall. That’s kind of juvenile, sure, but it’s also sweet and sincere. To me, it’s charmingly silly.

Plus, because Keyshia Cole sings the hook, the song has heft. Kalefah Sanneh once wrote that she makes love songs sound like “war stories,” and that captures the power of her gravelly, sensual voice. In “Boyfriend/Girlfriend,” you can believe she really needs the goofy dude who’s rapping to her.

So there you go: A fun, danceable track that lets us party like its 1991, yet also provides a strong vocal performance. Let the shaking of booties commence!
