"It is also a very good idea to use the appropriate relationships from the Alternative Version Relationship Class to link the other versions; sometimes one from Remix Relationship Class is appropriate instead. (In this case, the "single version" would be linked using Other Version Relationship Type or Remix Relationship Type to the one on the album. The direction is governed by which one is earliest.)" just doesn't apply here right now. Made other small changes for NGS stuff.
