Currently the Soundtrack style for tracks says:

"If the cover lists specific artists for each track, the listed artist should be placed in the Artist Credit field. Otherwise, use the release artist. For releases with no per-track credits, use the composer for each track instead. If the composer is unknown, use [unknown]."

This is confusing, because it gives two things to do if there are no per-track artists.

So, I propose the following correction:

"If the cover art lists specific artists for each track, that artist should be placed in the track's Artist Credit field. If there are no track artists, use the release artist instead. If there is no release artist, use the composer for each track instead. If the composer is unknown, use [unknown]."
