What is the classical piano song from Ep 13 08:39 of parasyte? I've tried so hard to find this song and am drawing a blank. It's killing me. I thought it may have been Beethoven but I'm not sure. Please help!
Sounds like Ave Maria to me —  not quite Schubert's version, though, I think.

It sounds more like Charles Gounod's version, which apparently was composed to be superimposed with Bach's Prelude No. 1 in C major, BWV 846 — so it may only be the Prelude itself?
