Among Hip-Hop purists Rap Music is a art form that is found in the wider culture of Hip-Hop
According to wikipedia "The term hip-hop music is sometimes used synonymously with the term rap music, though rapping is not a required component of hip-hop music; the genre may also incorporate other elements of hip-hop culture, including DJing, turntablism, scratching, beat boxing, and instrumental tracks"
The question at large is what is more valuable the culture or the art form? Additionally,
what is more important to the music: The bars (lyrics) or the beats (production)??
