"Music get more intense when game get more intense" you don't need lyrics to give a song meaning, but I've never heard a game song with meanings (I could just play some shitty games ig).
If you listen to "we will fall" by Iggy Pop and the Stooges, you'll get a very long song about... something? The lyrics are wet vague, but its the beat and attitude of the song that creates thousands of theories.
The point is, a song can be whatever you make it out to be, and that's why a lot I people listen to music.
