Miley Cyrus's Biggest Hit Single! Congradulations!

This Tuesday:
For Cyrus, the powerful sales figure will push her to a possible a top five debut on the Billboard Hot 100 next week. If she manages that, it'll be her highest bow ever on the chart -- beating the No. 6 entry of "The Climb" on March 21.

The good news for Cyrus doesn't stop there: she's also featured on the new Disney Friends for Change charity single "Send It On." The tune boasts Cyrus, Demi Lovato, Selena Gomez and Jonas Brothers.

"Send It On" hit digital retailers on Aug. 11 as well and could shift 70,000 to 85,000 downloads. If it sells that much, Cyrus may find herself with a pair of top 30 debuts on the Hot 100 next week.

This Saturday:
ALL-AMERICAN GIRL: Miley Cyrus blasts onto the Billboard Hot 100 just below the Black Eyed Peas with "Party in the U.S.A." at No. 2. The song can't top the title above it, but it does match "I Gotta Feeling" for the year's highest bow. The Peas' track began in the runner-up spot (to "Boom Boom Pow") on June 27. This decade, only two songs by solo females have started higher, and both became instant No. 1s for "American Idol" winners: Fantasia's "I Believe" (July 10, 2004) and Carrie Underwood's "Inside Your Heaven" (July 9, 2005).

The lofty launch of her new hit also marks Cyrus' highest Hot 100 ranking. She previously peaked as high as No. 4 with "The Climb."
