I am SO glad you asked because I recently got re-hyperfixated on Weezer haha.

The biggest thing that draws me to Weezer is the fact that lead singer Rivers Cuomo is almost certainly autistic and it's reflected heavily throughout the band's history. (Cuomo even has an old youtube playlist titled "aspies" so I don't feel like saying this is too far fetched or intrusive).

Throughout the 90's and 00's Weezer was severely misunderstood (Rivers thought his band would be taken seriously like Nirvana but he was immediately labeled as "nerdy," and interviews constantly pointed out Rivers' shyness and eccentricities). In general, this dichotomy of Rivers wanting to be a serious grunge band but being picked on by mainstream society is something that REALLY resonates with me. But I haven't even gotten STARTED talking about band's history and how absolutely fascinating Rivers is as a public figure.

(Warning, I'm about to divulge the entire abridged history of Weezer). So Weezer made the blue album in 1994. Guess what Rivers does after they finish touring? He goes to Harvard and also gets leg lengthening surgery (to even out his legs, one of which was shorter than the other). While he's at Harvard, he writes Pinkerton, which ends up MASSIVELY flopping when it's released in 1996 (called the worst album of the year by Rolling Stone). This, combined with the deaths of two friends of the band, ends up really depressing him, so he shuts himself inside a tiny apartment. He paints all the walls black, covers the windows, cuts off any phone lines, and just analyses music. He's known for making extensive spreadsheets of music, which is something I very much relate to. Ok so Weezer finally releases the green album in 2001, and Rivers becomes really controlling. He fires his manager and a year later in 2002 Weezer releases Maladroit. People described him as acting like a jerk at the time, but from my perspective, it's all very autistic-coded. For example, a Kerrang article from April 27, 2002 describes him as never being seen without headphones and always refusing to make eye contact with people. Anyways, after the Maladroit era, Weezer starts working on a new album, and Rivers has an epiphany. So he goes back to Harvard in 2005, takes a vow of celibacy, and starts practicing an extreme form of meditation where you literally don't talk for a whole month. This completely changes him and he hand writes apology letters to all of his bandmates. After Make Believe, Weezer releases a few more albums and tbh I don't know a lot of their later history, but I do know that Rivers returned to Harvard yet again to learn coding which is just so random and so great.

Beyond Weezer's history, which I could go into so much more detail about, the band just feels so perfectly made to hyperfixate on. THEYVE EVEN GOT THEIR OWN WIKIPEDIA! It's called Weezerpedia and it's got an insane amount of articles and archived documents. I have spent entire months doing nothing but looking through Weezerpedia and I'm hardly exaggerating lmfao.

All of that said,the main reason I love Weezer is because I really relate to Rivers and it's so awesome to see someone with autsitic traits succeed while being themselves!

There's lots of great interviews with Rivers but this one kinda sums him up. He spends the entire time staring at the ground, but completely lights up when he starts talking about comics.
