The Novakid look like they're going to be fully implemented in the next version, and I was thinking it would be neat to implement NPC musicians that play music. There could also be other bards throughout the universe playing their songs, but a I just thought the idea of a novakid playing the blues on a banjo inside the saloon would be super neat.
The saloon furniture piano thing already gets played by NPCs, which is pretty cool, but I think this is also a great idea! Maybe buying instruments from NPCs as well, or even playing music together...
The only problem with the piano is that it just plays a short tune and then stops whether the play or NPC is still sitting there or not, but if NPC's could just play their own instruments, it would be a lot better. If each race had different instruments they could spawn with, as well as each race having their own list of songs they could play?
