1) Because of personal biases and judgement towards rap
People judge different genres of music based on different personal thoughts and ideals. Therefore, there must be an overwhelming evidence to prove the power of rap. This is the only genre where the lyrics have even been used by professional lawyers to try to prove a case. Expert researchers
even bother to take the time having to explain and break down rap in order for people to accept that music alone cannot be actually used as evidence. The authors note, "it is significant that the recent usage of lyrics in criminal trials has been reserved nearly exclusively for rap lyrics
rather than for lyrics from other musical genres—even those which also contain references to violence or crime. Dennis (2007)
, for instance, identifies only a single case involving lyrics from another genre in the United States, while Tanovich (2016)
reports the same in a review of Canadian cases."
Even Will Smith, a fine rapper in his own right, admitted the power and pressure of being a rapper, standing in contrast against relatively easy pop/rock/other genres: "In rap music, you have to defend yourself. You know, rap music is really aggressive …. You’ll get chewed up and spit out if you’re not confident and if you’re not strong and assertive …. And there’s something in rappers’ eyes, there’s something that gets created in the eyes from having been able to create that defense through an offensive posture, and to be able to be in that space where you can sit in a room and feel confident and you don’t care what nobody says, and you don’t care how they come at you..."
Now, I won't go into too much detail as the rest of the research goes on and on about how exactly to interpret different rap, but the case is strong in the summary to prove the in-depth nature of rap, such that THREE EXPERTS have to spend thousands of words explaining what they mean: "The following discussion identifies four key dimensions of this context: (1) the socioeconomic context, (2) the criminal justice context, (3) the cultural context—both socially and musically, and (4) and the music industry context."
2) Due to inherent elements of rap
There are countless ideas that attribute to what rap is on a common basis, which are usually not attributed to other genres of music. Some data scientists
worked together to emulate rap, finding that "By scrutinizing the linguistic features that influence the participants’ authenticity judgments, it is shown that linguistic properties such as ‘syntactic complexity’, ‘lexical diversity’ and ‘rhyme density’ add to the user’s perception of texts being authentic. " Indeed, there has been an entire 200 page book
talking about how to analyze the entirety of rap, with the summary stating:
"In rap music, “flow” refers to a rapper’s delivery of the lyrics. This dissertation is a
systematic analysis of three main parameters of flow: rhythm, rhyme, and pitch. The first chapter
reviews the existing literature on rap and establishes a methodology of analysis and rap
transcriptions. Chapter 2 focuses on all rhythmic aspects of rap flow, including issues such as
rhythmic complexity and speed, rhythmic motifs, and meter. Chapter 3 is dedicated to dissecting
issues of rhyme, ranging from basic rhyme forms, to issues of rhyme regularity and density, to
rhyming in non-English rap. Chapter 4 examines vocal pitch as an expressive tool in rap music,
categorizing the ways in which rappers use the pitch of their voices to shape their music.
Chapter 5 features an extended analysis of a single track, “The Ringer” (2018) by Eminem. This
analysis demonstrates the various applications of the methodologies established in Chapters 1-4"
Clear as day, it's very noticeable that there is a lot of ideas that work their way through. In other songs, it's entirely possible to only focus on melody, rhythm, mood, since it can be instrumental, but lyrics are the key to rap, and the dissertation is extra proof that rap needs extra analysis to truly understand and appreciate, unlike other genres of music.
Conclusion: By using expert research instead of cherry picking rap songs, it is doubtless that my arguments are incredibly trustworthy and powerful. The fact that the experts in arg1 AND the expert in arg2 both had countless different perspectives on how rap lyrics can be analyzed, this depth is far, far beyond any of that in other genres. As such, the only conclusion is that rap holds the best, most complex, most meaningful lyrics.
