"Once More with Feeling" is one of the best episodes of modern television, period - musical or not, sci-fi show or not, part of the mediocre season 6 of "Buffy the Vampire Slayer" or not. When I first saw it, I was mesmerised. I happen to like a lot of the songs too, especially Giles' 'Standing', which was beautiful and touching. Joss Whedon created a masterpiece in the form of this episode with his songwriting skills (unexpected) and its wonderful plot. Lots of shows have a musical episode, but they are VERY risky. When "Oz" did it, it was fabulous as well, but understandably it is an easy thing to mess up. This episode should be revered and remembered for what it is.
