Normally I don't pay much attention to vocals, apart from shoutable choruses or especially nifty lines to quote when sharing a track, but sometimes it really pays to screen lyrics enough to get some idea of a band/artist's views. It's a sad reality, but these days it's the done thing for a lot, probably the majority, of bands to politicise their music. Or even just declare themselves as supporting one side or another even when their music itself was perfectly apolitical and about snake demons and rogue wizards or some shit!
Yeah, the lofty profession of pop music artists shouldn't get involved in the mundane world of having opinions.
Let's face it, all culture is bullshit and saying that they are in some other dimension and shouldn't upset their listeners by having opinions about stuff - that attitude is every bit as bullshit as them having opinions about stuff.
You're effectively saying that music is a commodity on the level of Coca Cola by saying that. Like you only want the cool refreshing taste of Coca Cola and don't want to be preached at by the Coca Cola brand. That's the message of "keep opinions out of music", since you've basically given up on the idea that music is anything more than a commodity that tells you a story or makes you "feel" a certain way that's entirely without context. All the meaning we ascribe to music: is fundamentally a sack of shit if you tell musicians they should keep their mouths shut for upsetting you.
And since you've already told us at this point that music is a load of meaningless shit, then why in hell are you even upset about it? Like, do you get upset that the guy flipping your burgers believes in QAnon? No. So, some dumb band singing about Warlocks or something, who cares what they think outside of that. They don't owe it to anyone to maintain a "100% professional non-partisan pro-warlock" stance at all times. That's just BS. It's weird thing where people are simultaneously putting them on a pedestal where it's this sacred profession where they have a duty not to have opinions like the rest of us, but at the same time denigrating them as being merely pop musicians so who cares what they think anyway.
If people don't want other people's opinions upsetting their enjoyment of stuff, they should live in a cave, not get upset that the consumerist items that they're purchasing have people with opinions who make them.
What is it: "I paid for a copy of your album so you should shut the fuck up with the politics stuff". That's also some extreme bullshit level of entitlement from someone for just buying into an album or an idea of a band. Like, people want to enjoy Metallica but they also want to be a Nazi, so if Metallica speaks out against Nazis, well that's just beyond the pale because now Nazis can't listen to their Metallica collection in peace. Well, fuck those guys for being lame basically.
