You mean the system menu or on the splash screen? For the splash screen your best bet would be to make multiple videos (of a static image if that’s all you want) with the music playing, and use the splash screen randomizer (https://www.petrockblock.com/forums/topic/splashscreen-randomizer/) to pick them randomly.
If you want it on the systems menu or Emulationstation as a whole, I don’t think it’s currently possible. Hopefully someone who knows more about Linux systems and ES/Retropie as a whole can give more help.
