"Glee" is only in its second season, but the show's cast is already rewriting the record books... Last month, they broke Elvis Presley's record as the act to score 20 top 40 hits in the shortest amount of time in the U.K..  Now, Billboard reports that they're beating the King again, this time Stateside.  The magazine unveiled their latest version of the weekly Hot 100 singles chart, and the "Glee" cast has six entries, bringing their total to 113.  Elvis had 108 entries in the chart's more-than 50 years of existence.  "Glee" reached the record number in less than two years, with their first entry coming in June 2009.  It should be noted, however, that Elvis started topping the charts in 1956, two years before the Billboard Hot 100 launched.Courtesy of Metro Source
