Why You'll Sing Along: Not only is the music fiercely catchy, I can also tell you that Felicia sings (and looks) like an angel; Nathan is hilarious and vocally strong; and to the shock of absolutely no one, including the isolated Yanomamo tribe in Brazil, Neil Patrick Harris just kills it. In general, there's a catchy quality to the lyrics (being full, as they are, of funny rhymes and smart metaphors) that is definitely reminiscent of "Once More, With Feeling." For the record, Barney himself testifies that the music sticks with you, no matter who sings it. "Before we started I [got] some scratch tracks that [the writers] had sung already, and I couldn't stop listening to them...I think the songs are just great."
What's Next: Will there be a sequel? "Only totally!" Actually, said Joss, there's no direct path to a sequel—no deals or scripts exist yet—but they're totally and completely open to the possibility if this first one works out, and he has a germinating idea for what happens in part two. When prodded on the topic, Joss said, "We're so busy talking about the giant Broadway adaptation, the much longer film version and the much longer musical commentary we're writing now, but...yeah, have I thought up the sequel? Yeah, sort of. And the one after that? Little bit. Actually, what we want to do is a sequel right away that's brilliant and then maybe another one many years later that's terrible."
