ELI5:Why does music sound random when you listen to it at a very low volume?

When you listen to music at a very low volume, you can clearly hear the lyrics, but the melody sounds really weird, as if the notes were random, even though you know the right melody in your head.

PS: I flaired as biology because it may have to do with the brain, but maybe it has to do with physics and the airwaves, sorry for not knowing.

At low volumes, many of the frequencies don't reach your ear at an audible level. The speaker may not reproduce everything perfectly, or some frequencies do not carry enough energy to make it all the way to your ear. So, the music sounds weird because it's incomplete.
