(Cross post from /r/AnimeOST, where I didn't get any answer)
I have a song in mind recently, I'm pretty sure it comes from a well known anime that is less than 10 years old, but I can't remember which one.
Do you know what it is? I made a quick music sheet here so that you can see a bit what it sounds like in my head, I unfortunately can't remember any more.
There are supposed to be Japanese lyrics on the music.
