So after weeks of hype (the White House! Oprah! Rolling Stone!), the music-filled series about a struggling high school glee club finally got its powerhouse timeslot (for an original episode) last night, so how did it do in the ratings?

Spectacularly: the show garnered a series-record 13.6 viewers and a 5.7 rating in the coveted 18-49 demographic in overnight metrics, according to The Hollywood Reporter. "Glee" retained 67% of  the viewers of "American Idol" and 79% of the singing reality show's 18-49 rating.

This is a huge jump from the show's premiere on May 19, 2009, with 9.6 million viewers and a 3.9 in the 18-49 demo, and above the series' fall season average of 7.1 million viewers and a 3.2 in the 18-49 demo.

Last night's show, titled "Hell-o," featured the songs "Hello Goodbye," "Hello," "Give You Hell," "Highway to Hello," "Hello Again," and "Hello, I Love You." The show marked the debut of guest stars Jonathan Groff (Spring Awakening) and Idina Menzel (Wicked), joining Broadway vets and series regulars Matthew Morrison and Lea Michele.

Next week's episode will be the much-hyped "The Power of Madonna" show, featuring an eclectic selection of the Material Girl's greatest hits: "Borderline," "Open Your Heart," "Burning Up," "Crazy for You," "4 Minutes," "Like a Prayer," "Like a Virgin," "What it Feels Like a Girl," "Express Yourself" and "Vogue."
