The rap goes beyond being just a musical genre is a form of expression, an art, a feeling.
There are exponents of this great genre who tell their stories and make you see the reality of life, others give you a positive message when you need it. A good exponent can make you open your eyes, raise your fist and think differently. An exponent capable of doing that not only becomes a good rapper, he also becomes a unique person, because someone with the gift of making them think differently, of making the lyrics of their songs feel like they are unique.
For me the beat is very important because the sound of the base can also make you love a song, whether it's a slow or fast beat. It matters how this is done and how you complement it with the rhymes, because rap is not just rhymes or lyrics, it is what the beat transmits to you or makes you feel.
Many think that what matters is the lyrics but the beat also has an essential function in a song, because without a good beat a song might not convey the message, not make you feel, not make sense of everything.
Without more anything to say this in my opinion and I hope to know yours in the comments,
says goodbye.
