In the context of Western traditional music mainly, where a lot of music is construed to be "symbolic" of ideas, principles, forces, feelings/moods, etc.
In a semiotic sense the sounds many choose are also "symbolic" of vibes, tropes, archetypes, signifiers. We gravitate toward certain themes like outlaws and badmen in general so their signifiers (trap houses and 808s, samples of violence and gunplay) get picked up - like with trap houses, Trap was originally drug den beats in the South - some of the worst places in America tbh. How to explain some guy in Sweden who makes trap and calls his white homies "My n***a" and shit lol?
So: if we consciously avoid associations, even tenuous ones, between sounds and meanings of any sort - social, visual, linguistic, anything - and let sounds be sounds on their own... a deeper appreciation and originality might result.
