Missing albums on Miroslav "Meky" Žbirka

[MineOnlyDiamond]

Hello, artist Miroslav "Meky" Žbirka is missing a few albums on his profile. These albums are:
Doctor Dream - 1981,
Miro - 1982,
Light of my life - 1982,
Like a Hero - 1982,
Giant Step - 1983,
Dear Boy - 1984,
Step by Step - 1989

These albums are not found on Spotify nor on official YouTube channel. I found only fan's uploads on YouTube, but album Giant Step, Like a Hero, Dear Boy, Miro and half of album Step by step is no where to be found. (I searched)
Also I found song "Nezvestná" from Miroslav Žbirka, but it isn't registered anywhere.
Could we get these albums and song on Spotify?
Thanks
