It would be really neat if we were able to play the orcenstrion songs we've collected in-game via the Companion app, turning the app into a real-life orchestrion!

I often stream music from my phone during work (and when I'm otherwise away from the game), and often wish I could shuffle or play songs from my in-game list. (ffxiv has such lovely music!) I currently have the digital soundtracks on my mobile devices to listen to, but it would be a fun "link" to the real world to have what we collect in the game impact what we can play when away from the game.
