"The Sing-Off" took the No. 2 spot on the iTunes Top Songs Chart today with Pentatonix's rendition of "Love Lockdown" by Kanye West. With only seven groups remaining, "The Sing-Off" continues to prove its dominance on the iTunes Charts week after week by showcasing some of the most talented musicians on television, including BYU's Vocal Point.

On last night's episode, the groups demonstrated their a capella strength by performing hip hop songs. Vocal Point performed Diddy's "I'll Be Missing You." The all-girl group Delilah reappears on the chart at No. 6 with their version of "How to Love" by Lil Wayne. They are also joined by Afro-Blue at No. 8 with their rendition of "Killing Me Softly with His Song" by The Fugees.

Pentatonix's version of "Video Killed the Radio Star" remains on the chart for its third week in a row, at No. 9. "The Sing-Off" also continues to dominate the top 100 Songs chart by holding 18 of the songs; more than any other television series on the list. In addition, "The Sing-Off" album from last night's performances also lands in the No. 3 spot.

It does seem a little disrespectful, though, to bet for or against a group from BYU, which frowns on gambling.

To save you some time, here it is:

AFRO-BLUE (Odds 2 to 1) – Washington, D.C. – This fun-loving ensemble from Howard University started as a class in the music department. They have plenty of soul, and all nine members meld together with beautiful harmonies, soaring solos, and a fresh look.

PENTATONIX (Odds 5 to 2) – Arlington, Texas – The five-member group has a modern style and draws influences from several eclectic electro genres, including dub step and garage house.

URBAN METHOD (Odds 7 to 2) – Denver, Colo. – The group, which includes a rapper, was formed by eight musicians whose individual sounds gravitate toward urban music. Each has extensive studio session work but has never previously performed together.

DARTMOUTH AIRES (Odds 8 to 1) – Hanover, N.H. — Dartmouth College's oldest a cappella group, is currently made up of 15 fun loving, high-energy guys with eclectic tastes and no shortage of quirky antics.

VOCAL POINT (Odds 18 to 1) – Provo, Utah – The all-male group is Brigham Young University's premiere contemporary a cappella ensemble. Their nine-man vocal firepower continually invigorates audiences and entertains fans with inventive arrangements, humor and remarkable vocal percussion.

THE YELLOWJACKETS (Odds 20 to 1) – Rochester, N.Y. – Formed in 1956, the University of Rochester YellowJackets are anything but old-fashioned and half the members are enrolled in The Eastman School of Music at the university. This fun loving group's mark of distinction is their bright yellow blazers and distinctive sound.

DELILAH (Odds 22 to 1) – Los Angeles, Ca. – This all-female a cappella group, which includes members from the first two seasons of the series, has been singing across the country, but still carry an unfulfilled desire to conquer "The Sing-Off" stage.
