Unfortunately, Spotify is not responsible for missing music and removals of music that used to be available. If there's an artist/album/song missing, it's because the label/legal owner doesn't want it to be on Spotify or it is not available in your country (anymore). I suggest reaching out to the label and ask why this album is not on the platform.
I just assumed it was a one-day gift on the day of release, so you could listen to the whole thing, or parts of it, or whatever. I managed to listen to 3 of the 6 CDs worth of songs, and it convinced me I have no desire to own the 6 CD set. Not even sure about the 2-CD "RAW" edition. I knid of like the Spotify sampler. Maybe Bob should consider a one-disc version. I'd buy that.
