Short answer = no...usually. Just because an artist has one dementia tune (a borderline one in this case) doesn't open the floodgates for their entire catalog of non-dementia. If it's added, someone is going to eliminate it.
The exception are the A-list artists we can't ignore. Example one are The Beatles. Their albums are here because Damaskas played a mess of their songs on one Dr. D. show in 1979 or whenever, so they went into the archive because Barry played them - and everything he plays goes into the archive.
David Bowie's work is also all too well represented, along with several others. Did I add it? No. But I got the message. A-list artists will have non-dementia here because "we can't have this song without this one; it would look silly". Or that's the idea, anyway.
It's not supposed to make sense. It's just my interpretation of what should be added because Wayne added this or that in the past and I'm going along with what I perceive as his intent. Common sense dictates the rest.
