Taran, speakers are not the only way to play music - any mechanical system that could generate vibrations in the audible frequency range could be used as a musical instrument:
Here is a simple Stepper Motor Music making tutorial with step-by-step build instructions, note frequency chart, and source code examples:
And a more detailed one with the math that, at the first glance, is way over my head could be found here: hackster.io/marialoidacanada/stepper-motor-music-5cfb15
The biggest challenge would be to turn mp3 audio into midi format, but there are plenty of online mp3 to midi converters. And, coincidentally, LVGL music demo lv_demo_music, that James linked, comes with a spectrum analyser script spectrum.py that uses one of the popular python libraries for doing such conversions.
I think that, once you are done with LRT project, and given all these code examples and a small pile of noisy V5 motors, you should be able to tackle this music thing with ease.
