I don't know why this is still questioned.
The level 50 to 60 GSM quests deal almost exclusively with you crafting a music box for a client. That's in-game lore. That's not something from a Hildibrand quest, it's not funny mail text referencing prior Final Fantasy titles, it's not "you shell out gil for aetheryte expenses even when you teleport to Anyx Trine".
There are canonical music boxes crafted by goldsmiths in Ul'dah.
Audio recording and playback exist, canonically, within the FFXIV 'verse. Within Eorzea, even, without any magitek or Garlean or Allagan technology.
...now, if the question is, "are the exact tracks, the ones we get to play as background music via the Orchestrion, canon?" then the answer is probably "no" with a possible "unless they are dissociated in-universe from their corresponding places and events out-of-universe" caveat.
Exceptions goes to silliness such as PA PAYA, PA PA PA PA PA PA PA PA PAYA~
