Hi Simon. I'm still unsure about the pros and cons of the two settings listed in my OP. Each one seems to be capable by itself of achieving my objective of ensuring that the Artist display in the Playing Now screen actually shows the composer name. Deleting my tagCustom setting doesn't stop this working if my tagFormat setting is still in effect.

Is there some subtle difference between these two methods?
