pub const RECORDING_INCLUDES: &str = "artist-rels+work-rels+work-level-rels";Expand description
What a recording lookup needs for performance, production and composition credits in a single request.
work-level-rels is a switch: work-rels first attaches each work and
artist-rels then asks for artist relationships both on the recording and
on those linked works. work-rels also exposes explicit parent-work
relationships on linked works, including classical movements.
