YouTube is processing the HD version which should have a better quality… Check later maybe if it is not yet available, should not take too long I guess. Anyway here is the link:
Edit:
Seems like HD is already available but the quality is not so good as in the original recording on YouTube for some reason.
It looks cool! 
Would you be willing to share the source code? 
No plans for that particular project at the moment. That said I plan to revisit some of my older projects and upgrade them to MonoGame 3.8. There is a chance I will publish some stuff during this process. I plan to record some of the visually more interesting ones and then upload the videos to YouTube.
There is a small chance I will have enough time to make some small game prototypes or even start making an actual game if a prototype seems to be interesting enough. We will see.
Looks cool! I like the bouncing ripple effects. Seems like it could be the base for a cool music visualizer.
Youtube uses heavy video compression techniques. They work fine for video where most of the screen isn’t changing much, like a video of someone sitting in front of a computer and talking. But the quality drops significantly when there’s lots of little things moving around a large portion of the screen, like confetti, snow, or your particle effects. See this video for more explanation:
XNA had some visualizationdata method or so for that, MonoGame has no implementation for that at the moment afaik…
Seems to be a nice idea but I don’t know much about how to get useful visualizationdata. Any ideas what I could look at?
Unfortunately, I wouldn’t know where to even start. I’ve never really learned anything about processing sound in code. Sorry… =/
I think I would try preprocessing the raw sound data and using the result and / or processing the sound data on the fly to get the frequency spectrum and then using this data in some way. Would be interesting but I will first revisit some older projects and try to get them to work with MonoGame 3.8 before I jump into something like this which will take probably a lot of time since I don’t have experience with sound.
