While I was gardening this morning I had my MP3 on shuffle - and one of the pieces I heard was the theme from The Gift, where Buffy dies - it remeinded me how much I love that music and how well it fits in with that final scene.
I love how some music really enhances a scene, and this one in particular is well written, so that only hearing the music brings back the devastation of the Scoobies ... and Spike's tears.
There are some films where the music is really beautiful, poignant ... whatever is needed, and so often, if it is well written, we fail to appreciate it.
