Bleak, soulless future is ruled by a supreme overlord, who by that era is unable to enjoy music since it was historically wiped out a century prior.
Curious, the overlord creates a trio a robots which each possess separate recording abilities as well as a mini-time travelling device. Their purpose is to go back in time and attempt to capture every known musical genre/defining musics that inspired generations.
Essentially it's an adventure each episode with a song towards the end that either resolves or attempts to resolve the plot. Robots record the sound and song and move on to the next point in time.
It's just a thought roaming in my mind, and I figured the ending would be that the music had influenced the robots beyond their designated program that once they return to the overlords, the music inspired a revolution and attempt to overthrow the dictator.
Just my take on trying to make a decent show that involves music, since those tend to suck.
