With mental attention, there's only so much focus a person can attain at any given moment, especially for long durations without rest. You're not necessarily listening to, picking out and analyzing every single note and every single sound you hear in a song, it's the combination of all of it which makes it music in the first place. If the "beat" or non-vocal part of the song is overwhelming a person's attention and focus and, like in the example you gave above, limiting the mental attention left over to focus particularly on the lyrics, the message behind the lyrics becomes, by definition, subliminal: accepted without question.

Once you get accustomed to accept this subtle form messaging, it becomes a habit that can be difficult to turn off or "unlearn." So people who listen to raunchy music in this highly passive way, with suggestive messaging more or less overlooked by their focused attention (messaging which they would otherwise perhaps be repulsed by) they're probably more likely to accept this subliminal "nudging" elsewhere in their life (advertising, television, government, peer pressure, cults, podcasts, political parties, etc.)

Kind of a hunch based on personal experience but also a generalization at what I see in "popular" culture at the moment.
