Man, I miss when Kanye was more than some idiot on TV.
He still is. Yeezus was a superb album. Possibly his best to date.
As to the other side of things: it's true of literally any genre of music. People sing about what inspires them. What motivates them to express their feelings to an audience. Love, sex, and social interaction is at the heart of the human condition. It's something universal that everybody deals with at some (or most) part(s) of their lives. So it's little surprise that it's going to come up a lot in art of any kind. 99% of Bluegrass is "I lost my love/my woman doesn't care for me, but I have Jesus so it's ok", just as 99% of oldschool country is "I lost my love/my woman doesn't care for me, but I have this bottle so it's ok", just as 49% of blues is "I caught my woman out with another man", and another 50% is "I'm having sex with a woman while her husband is away/my woman's husband caught me in the house and now I have to sneak out the window". What are the big Beatles hits? "I Want to Hold Your Hand", "She Loves You", "Something", "Can't Buy Me Love", "Please Please Me", "Ticket to Ride", "I Feel Fine". A butt-ton of music (the vast vast majority, I'd say) deals with love and boning because it's a hardship the vast vast majority of people have to deal with.
The thing I like most about Hip-hop is that its thematic roots lie in the civil rights movement and the realities of life in poverty/the ghetto. It's a different kind of hardship. I find myself gravitating towards the more socially conscious artists like Tribe Called Quest, Nas, The Wu Tang Clan, Biggie Smalls, 2Pac, Kanye and the like precisely because what they are expressing is something so fundamentally different from what you get in most other genres. And more importantly it's done without the pretension of the Claptons and Lennons of the world.
It's precisely why I don't like so-called "bro-country". It feels cynical. It feels inauthentic. It feels like a boardroom full of writers with a checklist of buzzwords that need to be hit in order to achieve maximum penetration of the pop charts. It's not music, or at least, not the sort of music that is appealing to me. The thing I like and gravitate towards in music is rawness. When you hear Hank Williams or Johnny Cash sing you can hear the sorrow pouring out of every line. You can hear the abject misery and heartbreak in every line of an Etta James or Sam Cooke song. You can hear the decades of hard life Muddy Waters lived through in his slide guitar play. And with guys like Kanye and Nas and Ice Cube you can hear the rage, the disgust, and the outrage for what white society has wrought on the black world. That is power. That is moving. That is interesting.
And it doesn't all have to be sad, of course. I also love the haughty braggadocio of
The Wanderer or
Built for Comfort or the joyous cheesiness of
You Got What I Need. To me it just has to feel like it's coming from a genuine place. It may be that I'm just disdainful of more heavily produced works. But there you go.
