Symphony

A rhythm game that combines Clone Hero with Geometry Wars. A weird digital demon has stolen the souls of all the worlds best composers and you have to shoot down enemies to the rhythm of the song that you pick. As long as it's an MP3 file, (and over 1 minute and 30 seconds long) you can play it in this game. I've defeated digital demons to the dulcet tunes of Weird Al, SiIvaGunner and various Friday Night Funkin songs. Seriously, this game is only as good as your musical tastes.

best one I've found for my music aside from beat saber

It's an OK retro arcade shooter with some unlock and ship configuration mechanisms. The real feature, of course, is the way it makes levels out of songs. Helped me to get reacquainted with my ancient music library, but also made me afraid of any sweeping refrains in my songs. Interface for browsing songs and such seemed pretty bare bones and the game didn't seem to like alt-tabbing when I was trying to make sure it got all my folders, but it's fine for what it is.
