Eminem’s second single from his Recovery effort makes a huge debut this week. His collaboration with pop starlet Rihanna, “Love the Way You Lie,” opens at No. 2. Usher‘s “OMG,” slides back a spot to No. 3. B.o.B’s “Airplanes” does the same, moving to No. 4. Travie McCoy’s “Billionaire,” backs into No. 5. And Drake’s “Find Your Love” also falls a slot to No. 6.

Mike Posner’s debut smash “Cooler Than Me” moves up one spot to No. 7. Ke$ha‘s “Your Love Is My Drug” falls two to No. 8. Lady Gaga’s “Alejandro” also slides back two places to No. 9. Jason Derulo gets his third hot 100 top 10 from his self-titled debut album. His “Ridin’ Solo” jumps up six places to No. 10.

Again, Eminem has a strangle hold of the chart. How long do you think it’ll be before he pushes Katy Perry to No. 2?
