Where's the love for the ferret?

I think the show is more successful when they're doing songs from the 70's. I've really enjoyed some of the modern music (No Air, Golddigger), but there's just something special about the older stuff. Maybe it's that literally all of America knows it, and I feel a sense of camaraderie? I don't know the show tunes that they do, and my parents don't know the modern music. But the 70s, we know.
