Does anyone know if there's a piano version of "No Answer" (track 18, from OST 2). Another track that has the same theme is "Anticipation" (track 7, OST 2). I'm looking for a piano version of that theme, it plays in so many episodes I can't believe it's unreleased. I've been unable to find any covers of this song either. Is it possible for someone to rip that track without the vocals or SFX in it?

i'm looking for Pastorale Rondo with the flute added
