Considering the series has already spawned two soundtracks, it would be easy to say that Glee music has been the key to this show's success.

But co-creator Brad Falchuk says otherwise. In an interview with Wired.com, he pointed to the Fox hit's emotional core as the basis for its buzz and its ratings so far.

"One of the main pitfalls of any theoretically “niche” show is that you spend too much time on the “niche” and not enough time on the “show.” We make sure that our stories and characters are compelling first, then worry about the music... what makes people interested in hearing it again and again is that it evokes the memories of the emotional experience they had with the characters when they heard the song on the show," Falchuk said.

Below, readers can catch up with some of the best scenes/lines from the first 13 episodes of Glee:

What else does Falchuck say about his brilliant creation? Excerpts from the interview follow...

On creating the characters: Our idea was always to use the stereotypes as starting points — something to make the audience instantly relate to the characters. After that, though, all bets were off and we just try to make them as real as possible. I love it when characters surprise you, just like real people.

On Chris Colfer as Kurt: Any great character is the combination of a brilliant actor and the right writing. He’s much sweeter than Kurt is, but he’s also very wise beyond his years. Writing for him is a blast, because you can basically give him anything and he’ll make it work.

On Terri: I don’t think Terri is deplorable. If you watch her scenes carefully you’ll see that she’s usually right in her assessment of the world and her relationship. She says things many women think about their lives and their spouses. She’s just very honest and selfish — not always a great combination. All of it is fear-based with Terri, though. She’s so scared all the time and certain creatures lash out when they’re scared.

Glee is on hiatus until April 13. But fans can get an idea of what's in store by visiting our section of Glee spoilers. Enjoy!
