This was a dim background theme of some murder videos. I heard it now and then, during many months, and little by little one point -- from 0.26, three rising notes, and then an exquisitely fine series of some high notes -- began to attract my attention.
The rest of it did not sound as fine at first, but now I accept it all. It could even be the background music of Rosalia, but in that case those fine high notes should be repeated a little later.
So I sometimes listen this as background music.
