Week of August 29

This week's chart activity is dominated by two rap artists. Rapper Pitbull pulls off the feat of earning his first two Top 10 hits in the same week, with his guest appearances on Enrique Iglesias' "I Like It" (14-9) and Usher's "DJ Got Us Fallin' in Love" (15-10).

Meanwhile, Eminem earns his first Top 40 hit on my charts, as his duet with Rihanna, "Love the Way You Lie," debuts at No. 36 in its clean version (explicit language edited out). I've struggled with charting this song because the first time I heard it a couple of months ago I wondered whether it was exploitative, given Rihanna's personal history with domestic violence. But over time, as I've listened to the lyrics, the song has resonated with me as an honest portrayal of the emotional tinderbox of an abusive relationship. It's certainly caught on with U.S. buyers and listeners, as it's reigned at the top of Billboard's Hot 100 for a month and a half.

Elsewhere on the charts: Donna Summer earns her sixth Top 40 hit of the 21st century with "To Paris With Love" at No. 40. Her biggest, "Stamp Your Feet," was the No. 1 song of 2008; John Mellencamp returns with "Save Some Time to Dream" at No. 39. He's placed 32 songs in the Top 40 in the past three decades, with his most recent No. 1 being 1997's "Key West Intermezzo (I Saw You First)." And Michael W. Smith enters with "Save Me From Myself" at No. 37, his first hit since the rebound "I Will Be Your Friend" went to the top earlier this year.

At the top of the charts, Katy Perry's "Teenage Dream" caps its five-week sprint by moving 2-1. That rise was almost as fast as her chart activity with "California Gurls"; the Snoop Dogg duet (which falls out of the Top 40 this week) went to No. 1 in four weeks.
