Yes this would be awesome. Like you said, not only for Bards, and second GM, but really for those Groups where 1 player is more adept at audio and can take that task off-the-hands of the GM, free up time and headspace for the GM to focus on running other features. By the way Tristian for now, you may be able to simulate it and achieve something similar (to an extent, with some prep work) using Roll20 Pro subscription and the API Mod called Roll20 AM (Audio Master). Essentially you have to program a Macro with the !Mod Command for each sound, and allow Player(s) to trigger that macro. This works for giving the Bard a dozen sounds to trigger at-will, but doesn't solve the issue of letting a secondary player organize and choose the overall entire jukebox. Still a great suggestion for a Roll20 feature for everyone without using a Mod.
