Ok, just addressing the key points here.

It doesn’t seem like you’ve really listened to much of the band or you would hear a distinct sound/motifs reminiscent of their garage rock days, or riffs/motifs from other songs that they frequently call back to, connecting their discography. Even characters in the lyrics are shared between albums.

Next point, bad lyrics? Depends on which song. Some songs are repetitive, some simple, and some that are 100% narrative driven. What Gizzard is excellent at is telling a story, which is what really makes a great song great imo.

Multiple genres isn’t bad, especially when they do them so well. I grew up listening to thrash and stoner metal, and they’ve put out some of my favorite songs in those genres. I could understand if the music was shit, and was produced in volume only to make more money, but that isn’t the case. They shelved an album for 5 years until they felt it was right. I really appreciate their output honestly, I don’t need 5 albums a year but like, wow. Compare that to being a tool fan, I had to wait 12 years for the last album to come out.

As for feeling that you shouldn’t have to see people talk about them so much…..keep scrolling? They’re talked about because their great, and they seem to have a lot of fun making and playing music.
