My tongue dances behind my lips for you.

Songs new to Billboard's Top 50 singles chart, and the top debut.

#31 (from #60): Lil' Wayne, "A Milli"
Whether the vocal's a freestyle or an incredible simulation, I'm not sold on the repeat entertainment value of a great rapper's improv. I might feel different if I was sold on the beat.

#47 (from #51): Flyleaf, "All Around Me"
From about.com - It can take a while for an aspiring band's music to finally kick in with a general pop audience, and alt-metal group Flyleaf nicely illustrate the point. Their debut album appeared in October 2005. It is the collection's 3rd single that is finally climbing the pop charts admirably filling the current rock niche on top 40 radio. Fans of the band Daughtry will recognize producer Howard Benson's palpable influence here. Rock, are you going to just lie there and take this?

#50 (fromt #56): Carrie Underwood, "Last Name"
Theme from What Happens In Vegas.

#57 (debut): Madonna, "Give It 2 Me"
Pharrell, like Timbaland, is giving her his best autopilot - the primary distinguishing feature being Pharrell's fondness for goofy jazz keyboards. Madonna's autopilot has seen better days.
