This screams PS3 limitation.

By my calculations (assuming we're sticking with the OGG format used in game), with 47 Orchestrion rolls out there, to load every one into memory on entering the house/inn/zone, you're looking at about 235MB, which is basically nothing by PC/PS4 standards... however, the PS3 has 256MB of system ram...

... I know they wanted to have "each track load quickly" (on PS3), but the best experience for everyone would be have the previews (10~ish seconds of each scroll) load in at reduced quality, and then when you chose the track you (PS3 users) might have to wait 5-10 more seconds for it to play at normal BGM quality (PC/PS4 users would likely be instant, this whole "issue" is most likely about platform parity).
