This is a place to help mo collect all the ARs people seem to be missing. --kuno.

• I used the "has additional guest other vocal performed by" AR but I feel it is wrong. Is there something like a "sampled speech" AR? (asked by gioele on IRC, copied here by me --kuno).
• I would like some way to indicate that a track is a live performance of some other track in the DB, this was already suggested by someone else on the OtherVersionRelationshipType page. --kuno.
