Maybe I'm the one that's confused.

I might have mistaken it for another track. Or, maybe I liked the music enough that it made up for the vocals.
It could be that this album needs more time than I've given it. I mean I've probably played it 4 times in the ~17 years I've owned it, maybe it's just hard to digest and hasn't sunk in. And I was "working" while playing it, so I didn't give it my full attention either.
