How much does it matter that you can barely make out the vocals on most of this record?

I don’t listen to words in my own language. I love their stylings and the musicality they impart with their singing. I don’t feel like their lyrics are the goal. It’s just another instrument.

Yeah, I agree. I'm listening with lyrics up and appreciate some of the musings. I don't think their ambiguity sonically detracts from the album though.
