NEW DIRECTIONS: Following the series premiere of "Glee," two songs by the show's cast debuted on the Hot 100 dated June 6, 2009, led by its highest-charting title to-date, its cover of Journey's "Don't Stop Believin' " at No. 4.

One year and three weeks later, the "Glee" cast had totaled 64 charted titles, the seventh-most appearances among all artists in the survey's archives and second among groups only to the Beatles' 71.

With the series' second season premiere set for Sept. 21, the TV troupe could soon pass the Fab Four for most Hot 100 entries among groups all-time.

Here is a look at the acts with the most Hot 100 appearances to-date:

108, Elvis Presley
91, James Brown
74, Ray Charles
73, Aretha Franklin
71, the Beatles
67, Elton John
64, "Glee" Cast
63, Stevie Wonder
60, Jay-Z
59, Lil Wayne

DEFYING GRAVITY: One of the songs that the "Glee" cast has sent onto the Hot 100 is "My Life Would Suck Without You." The ensemble's version reached No. 51 in December 2009.

Earlier last year, on the Feb. 7 chart, Kelly Clarkson's original recording of the song vaulted 97-1. The cut was the second song following the Hot 100's 50th anniversary to establish the mark for largest chart leap to No. 1, following Britney Spears' "Womanizer," which bounded 96-1 in October 2008.

Here is a listing of the songs to make the biggest vaults in the Hot 100's history:

Positional Gain (Chart Move), Title, Artist, Year
96 (97-1), "My Life Would Suck Without You," Kelly Clarkson, 2009
95 (96-1), "Womanizer," Britney Spears, 2008
91 (94-3), "Beautiful Liar," Beyonce & Shakira, 2007
88 (95-7), "Smack That," Akon featuring Eminem, 2007
85 (96-11), "Cowboy Casanova," Carrie Underwood, 2009
85 (100-15), "Jai Ho! (You Are My Destiny)," A R Rahman & the Pussycat Dolls featuring Nicole Scherzinger, 2009

This March, Taio Cruz rocketed 53-1 on the Hot 100 with his maiden chart entry, "Break Your Heart," featuring Ludacris. The song's coronation marked the biggest jump to No. 1 for an artist's first Hot 100 charted title, passing Clarkson's "A Moment Like This," which roared 52-1 in 2002.

THAT'S A RAP: On the Hot 100 dated May 22 this year, Eminem bowed at No. 1 with "Not Afraid." While the song was the 16th to start at the apex, it became the first rap title to earn the honor.

Eminem has since returned to No. 1, holding sway the last two weeks with "Love the Way You Lie," featuring Rihanna. The song is the 988th Hot 100 No. 1, continuing the march toward an upcoming milestone, the as-yet-unknown 1,000th Hot 100 leader.

Will that landmark song be by an artist who's enjoyed a view from the top before, like Usher or Justin Timberlake?

Or, will it be by a star artist who's yet to achieve the distinction of a Hot 100 No. 1, such as Taylor Swift or Justin Bieber?

Or, by an act, like Lady Gaga just two years ago, that's yet to appear on the survey?

The fun will be in finding out, as it has been every week of the last 52 years in the pages, in paper and online, of Billboard.
