1. Play Pa-Paya in an Orchestrion

If you play the Pa-Paya song in the Orchestrion, it plays for an absurdly long time (haven't tested length). During the time above, I found that, after waiting for 10 minutes in my Free Company's house, the Pa-Paya song would keep playing well after it should have been reset to the next song. I checked it over multiple times to make sure it was not on repeat or something similar, then we finally manually changed the song to another and removed Pa-Paya from the playlist. I haven't tested if it's restricted to FC housing or the Lavender Beds, but my friend (on PS4) experienced the same in the same house, so it's not client-side or restricted to PC or PS4. When accessing the Orchestrion during the song, it registered that it was playing Pa-Paya, not any of the other songs that were on the playlist. All other songs in the Orchestrion played as normal (not extensively tested).
