There not objectively bad but I do think Thom Yorke’s plaintive melancholy dirges benefit a lot from the way Radioheads rhythm section and Greenwood’s instrumentation transform them into something new. They’ve also kind of hit a late/mature stage groove since in Rainbows where I don’t think they really push themselves the way they used to, and their music is becoming less interesting and more predictable.
That they are ‘objectively bad’ is a classic hot take, although usually in response to their crossover appeal/ the amount of ‘normie’ listeners they have, rather than there being Zionists.
Nick Cave is another one whose come out recently refusing to boycott Israel (I think he likened the pressure to bullying or something ridiculous).
Peoples politics are really made by experience. Like a lot of actors for example have reasonably left wing politics because, at some point early in their career they often did experience struggle and exploitation. But a rockstars life is about as pampered as you can get, and the ones that are successful usually find success while their young, so it’s not surprising so many of them have shit politics.
