January is usually a particularly sad month for pop music. Coming off the industry’s big-release-heavy fourth quarter, the top of the year is usually a time for new acts. This year, however, is rolling out a bit differently. Pop starlet Britney Spears is set set to drop new single “Hold It Against Me” on Jan. 11, and Kanye West and Jay-Z will debut “H.A.M,” the first single from their collaborative Watch the Throne effort, that day as well.

At this point, little is known about Kanye and Jay-Z’s collab. Kanye sort of let the cat out of the bag earlier this week, but cleared up the confusion last night by tweeting the single’s artwork and release date. With several crowns and vicious dogs barking, it’s a regal one, indeed. They’ve remained pretty tight-lipped about the record’s sound, opting not to reveal who produced it or even what the acronym stands for. On the other hand, there’s plenty of info out on Britney’s “Hold It Against Me.” As we reported last week, it was produced by hit-makers Max Martin (“DJ Got Us Fallin’ in Love,” “Dynamite”) and Dr. Luke (“California Gurls,” “We R Who We R”). A demo with singer/songwriter Bonnie McKee’s vocals leaked yesterday. Its knocking bass is not unlike the smashes those two producers flooded the airwaves with in 2010.

Check out our poll and read what Britney had to say about her single after the jump.

Spears confidently tweeted that her version is even better, saying “Heard an early demo of my new single leaked. If u think that’s good, wait til you hear the real one Tuesday.” So the question is, which song are you more excited to hear? Are you dying for the latest from one of pop’s leading ladies? Or are you more anxious for what hip-hop’s royal twosome do on mic?
