“Shake Ya Tailfeather” from the “Bad Boys II” (Bad Boy/Universal) soundtrack cruises to a second-straight week atop Billboard’s Hot 100. However, Nelly, P. Diddy and Murphy Lee would be wise not to get too comfortable as Beyoncé is making another run towards the top.

“Baby Boy” is proving to be a hit in both mainstream and urban markets, and gains 7-5 this week on Billboard’s Hot R&B/Hip-Hop Singles & Tracks roundup. That tally’s No. 1 is Pharrell’s “Frontin'” featuring Jay-Z for a fifth-straight week.

Trapt’s “Headstrong” reenters the Hot 100 at No. 49. The song had previously spent 20 weeks on the tally and peaked at No. 52 in May. The cut reenters the chart thanks to a heavy increase in radio airplay at top-40 stations.
