Thanks, you brought me luck:
As I must have forgotten to stop free access to one full length Youtube video of just my Kindertotenlieder, I was surprised this morning finding the first of them used as accompaniment by a highly respectable singer (I find) named Gustavo Monastra:
He's asking me to sell him my orchestral Revelge playback too.
The only shock: He's already published 2 Youtube videos using my long forgotten piano version of Revelge (I had enregistered last year long before I decided to do the orchestral ones). One of them in the low voice key (c minor) in which I had published it, the other one technicallly upshifted by him to d minor causing a terrific distortion making it sound scratchy like a phone call. So my first reaction after saying thanks was my urgent demand to remove it and replace it by a better sounding d minor version done by myself without paying for it.
So my Mahler project won't make me a Dagobert Duck, but maybe I am wrong thinking that there's absolutely no market at all....
