In just 18 months of appearing on the charts, the Fox TV series has set the record for the most songs on the Billboard chart in the chart's 52-year history.
This week, "Glee" debuts six songs on the chart, giving them 113 songs in total - five more than the now second-place Elvis Presley, who had 108.
Lady Gaga also makes history on the chart this week; her new song, "Born This Way," becomes its 1,000th No. 1 song.
The Grammy winner calls the milestone the "greatest honor of my career."
