My pleasure, it's been a fascinating exercise, and a way to be "at the piano" while resting from some tendonitis in my arms.
I have similarly now typeset all the piano music (including songs) that I could find of
Alexander TSFASMAN https://musescore.com/artist/alexander_tsfasman-275506
Mikaél TARIVERDIEV https://musescore.com/artist/mikael_tariverdiev-23490
and all piano music plus many many songs of
Arno BABAJANYAN https://musescore.com/artist/arno_babajanyan-269868
(he wrote music for about 250 songs, and I've covered what I believe to be the most famous)
Plus a miscellany by
Artur POLONSKY https://musescore.com/artist/artur_polonsky-295790 (his arrangements may be found too)
Yuri SLONOV https://musescore.com/artist/yuri_slonov-273468 (A big thank you to Gamma for alerting me to Slonov as I was ploughing through the various Russian/Soviet online archives).
Isaak DUNAYEVSKY https://musescore.com/artist/isaak_osip ... evsky-6892
Other special interest collections that I've touched on are found as "sets": https://musescore.com/user/4151271/sets

* Note other people have contributed Tariverdiev and Babajanyan scores and arrangements. You may find other scores by the above composers on Musescore, but linked to different versions of their names. At this time, musescore does not have a composer index to link translations to canonical names.
