As a general rule (assuming they’re not e.g. autistic in the “difficulty processing speech” kind of way), native english speakers are expected to at least notice the lyrics of an english-language song they like. Honestly haven’t listened to a lot of NIN music, but IIRC they vocals are usually fairly clear and if they’re often the way OP is quoting, you definitely look like an idiot if you’re completely ideologically opposed to a band like that and still say that you’re a fan.
