This was mentioned in the now closed Artist Equivalence thread, but is still an issue.
In my library, I show Prism as 2 artists, one displayed as all caps. Their early work seems to be under the lower case artist and the later work as all caps.
I checked Allmusic and it shows as 2 artists as well.
First, as you can see, the 4 albums in my library show here as Appearances.
Second, under Tidal Main Albums, only the first Prism (Remastered) is correct. It hasn’t been added to my library yet.
Third, the rest of the Tidal Main Albums belong to other Prism band(s). Also, none of the Singles and EP’s belong to this Prism.
If you select the two links in my initial post, they seem to have the correct information for the Canadian Prism and the other Prism, whoever they are.
