Other uses for Orchestrion Rolls (PvP, FATEs, etc.)

One of my favorite collectables in this game are Orchestrion Rolls because this game has incredible music. However, as it stands the only uses for them are relegated to housing, and the Island Sanctuary, and the more 'ambient' tracks really lend themselves to this. But what about the slew of awesome battle tracks that we have? They're great, but sometimes it's not really ideal to be sitting in your house relaxing and chatting over Stormblood's 'Triumph' or managing glam plates at an Inn listening to 'Metal: Brute Justice Mode'.

I think it would be cool if we could make playlists that shuffle for content that we often grind, like Crystalline Conflict, FATE boss battles, etc. They have great tracks, but like a great Reuben sandwich; I can only eat it so many times in a week.
