Crying Alone

This by Yuki Kajiura is partly a slower instrumental version of her Song of Storm and Fire (in the violin portion), which it is intended to complement, and works very well for piano and solo violin. Yes, it's sad, but quiet and thoughtful too. It comes from Tsubasa Chronicles (nothing to do with the similarly-named Tsukasa from .hack/sign).

It almost feels like a rainy afternoon spent indoors alone, watching the raindrops slide down the window-pane. At least that was what came into my head while I was listening, but perhaps that's just me...
