Lyrics are both as important and inconsequential as any other piece of a song, they can make or break one the same way a sloppy guitar or beat can. I pay a lot of attention to hip-hop lyrics. An artist's rhyme scheme matters to me, their message, a huge list of things I think I would probably be incapable of listing. Something I'm in love with - and I'm not alone here, obviously - is when a hip-hop artist surprises me, they wrap one word around another and a rhyme emerges where my head wouldn't have found one ordinarily. See the beginning of i by Kendrick Lamar:
I done been through a whole lot/trials tribulations but I know God/the Devil wanna' put me in a bowtie...
When he rhymes "God" and "bowtie" there's a mechanism that clicks over in my brain, it processes what's going on in a brand new way.
There's something about this that brings me into the song, it makes me a part of the whole process, all the way back to when it was written, right up to the literal act of it entering my ears and sizzling up into my brain. Feeling like you're right there with a piece of art is one of the best reasons for art to exist, and it's absolutely one of the best reasons to make art. Not that I feel responsible, or like I in any way contributed to Lamar creating this song, but I'm interacting with him and with what he's created. It's not just there, outside and untouchable.
It really does remind me of how, when reading a comic, your brain will fill in action, it will add motion and depth to things that are completely still on the page. And when it happens it can send a bolt of energy directly into that place we all carry around, the place that needs to receive energy. There are words for it, but I'm not sure any can even touch something like that.
