That’s the magic of an .mpl file. It’s not a song you listen to directly. It’s a recipe for a song, meant only for Mario Paint Composer. Lose the program, and the .mpl is a locked diary. Keep the program, and you hold someone’s musical memory.

Perhaps the most technically specific use of the .mpl extension is within the (Advanced Video Coding High Definition) format. This is a file-based format for the digital recording and playback of high-definition video, co-developed by Sony and Panasonic.
