Someone from PSA will have to answer your question.
Meanwhile, for what it’s worth, here is how I save time when adding titles to the Playlist. The majority of SACDs have also been issued as CDs (or vinyl records). Click on “Search for disc data” and enter the title; if the disc is not found, you will (often) be offered the choice of looking in Discogs. I find that if I enter only the title, not the artist, I get offered the Discogs option more frequently. If a CD or LP version of the album is located, choose it.
I do a quick check to be sure the tracks are the same (no bonus tracks or whatever). Even if I have to do a little editing, this is still far faster than typing everything in manually. In many cases the SACD cover is the same as the Redbook CD. If it’s not, as with the MOFI SACDs with the MOFI banner across the top, I locate the appropriate image and add it manually. Of course not everything is in Discogs, but this method has saved me a lot of time.
I have recently added the following SACDs to the Playlist. Do they show up for others who have the same ones?
MOFI titles: Dylan John Wesley Harding; Parsons Grievous Angel; Dire Straits Brothers in Arms.
Others: Dusty in Memphis; Scheherazade (Living Stereo, recent Analogue Productions reissue); Exotic Dances from the Opera (Reference Recordings).
