Artist credit in musical theatre [theatre], add artist, or "and chorus"

[cricketco]

On the other hand . . . YIKES! What have I gotten into?

Is booklet a good source for Soundtrack track artist credits? [STYLE-1005]

Thanks Kid_Devine, that seems to amount to “This is what the SG says”. I’m trying to see what the benefits of not using the booklet info is. The only benefit I can see is that previously added Releases, where the booklet was not used, would be only medium quality data if a change to using the booklet was made. Can others be seen?

Comparing track and recording artist credits on:

and:

Or:

and
https://musicbrainz.org/release/db56b33e-c97a-35d7-a1c7-b9f3d2e80ba5

makes me think I probably did it incorrectly on:

Please advise!
