That’s why every top song is just a person talking over a beat, usually with the same kind of vocal style, usually the same kind of beat.
It’s really hard to sing the word “Lamborghini” and have that fit into the lyrics and be heard clearly and have the brand image positioned correctly.
It’s also a waste of advertising space to have any duration of a song not include clearly spoken lyrics.
Taking this example, DaBaby’s “Rockstar” sounds basically identical to hundreds of other recent songs that follow the same format of a person talking repetitively over a simple beat (every Drake song for example). Five possible instances of integrated advertising in the lyrics: Lamborghini, Chevrolet Suburban, Maybach, Glock, and Apple FaceTime. 2 of them in the chorus.
So what kind of music will people accept, that maximizes spoken word duration, speaks those words clearly, provides brand image maneuverability within the lyrics, doesn’t distract from the lyrics, and won’t have a fatal loss of integrity as a result of obvious product placements?
That list of requirements leaves us with basically one style of one genre, and it’s this style of rap / hip hop. To any extent that a song deviates, it becomes less effective as a channel for advertising.
I think the most convincing piece of evidence in support of this is this lack of differentiation among artists, even in terms of vocal style. In ‘90s hip hop every artist had a completely unique style, all present-day hip hop fans love all of those legendary artists... and yet, every modern artist is just mimicking the exact same cadence as Drake or Kendrick Lamar.
None of this can be reconciled with the notion that songs becomes popular purely because people like them.
