Hello @John_Wimer, you’ve removed Bowie from the main album data, but he’s still assigned at the track level. In this case, for every track.
This KB article talks about bulk editing…
Select all your tracks (right click or long press on one, then select all in the “1 selected” drop down). Now click on edit, edit the tracks, and edit metadata. You’ll see Bowie listed in the credits and can remove him (and add Dave Jones if you wish).
