I can understand why old music makes up most of the market, really. More exposure. The radio plays the same 20 songs every day. The same 9 songs are in every movie coming out. Also, newer artists don't have a clear musical identity. Country music, for example, began to suck back in the 2000's. I don't even know what the heck they're trying to get their influence from, rap or pop? They were all market chasing. IDK, man, it's not great. And newer artists will change themes so much or tones in an album it hurts. I was checking out this power metal band, they're cool, but the front man is trying to look like Bruce Dickinson and trying to sound like him. It ruined the experience after I caught on to his antics.
A blues guy I was checking out, the album was all over the place. He's crying about nothing, then the tone changes to storming the bar. It wasn't great and it wasn't coherent. I'm always checking out new music and find myself disappointed quickly. Honestly, I did like the theme for the new Spider-Noir show though, but for all I know it's something different next time.
Then there is AI music. That makes me nuts.
I also found an all chick metal band just to learn there was a dude writing all the music and just hiring female musicians to play the music. That sucked becuase the music was marketed differently.
Honestly, the two newest groups I like right now are Borknagar and Ghost. Both of the bands came out in the eary 2000's, late 90's. Borknagar is like a progressive black metal band that has great melodies, very forklore like sound. Ghost is the whole band rocking and it is not too distant from Alice Cooper's hard rock. Yet they play metal subgenres while keeping their musical identity. It helps when everyone knows confidently what they want to play.
Like, I know what I want to play. Power metal with thrash elements. It's fast, and there is room for the music to breathe. I got power chords that take barres to send the emotion forward and melodies that add tension and provide relief. I'm just working on the speed parts that give the rhythm tight timings. A lot of people who like the music I do just want to play faster and sweep the fretboard. Power metal isn't fast; it breathes. Thrash metal isn't aggressive; it grooves. Having an identity that is coherent and consistent doesn't seem to be the goal of new music.
Thanks for reading, and be safe.
