'Light Up My World,' 'Glee's' latest original song, makes its debut

glee-hell-o-320.jpg "Glee" did so well with an entire episode devoted to original songs -- the aptly-named "Original Song" -- that writers have added yet another brand spanking new number to the season finale.

That episode -- in which our Glee-sters head to New York for Nationals -- airs on May 24. The new song, "Light Up My World," is sung by the New Directions ensemble and is a bass-thumping dance number primed to be a signature song for the upcoming "Glee" summer concert tour.
