Includes bumping spawn velocity to get the "throw" on beats, with vfxgraph linear drag preventing runaway and then letting small amount of fluid sim/curl noise force give the particles life/motion as die off. Emissive brightness from particle speed, so the beats and bigger throws lead to brighter particles that then fade off (but glow for longer) - including size into fading value so that the bigger particles fade slower, for variety and to give a sense of "heat".
