Got to disagree with you there Spleen Cringe, words are what make a song a song, without them it's just a tune!

I can also tell you from many years experience that you don't have to 'compromise the sound' to make sure the words are heard! Interestingly, I've just had a look at a youtube video of Wolf People,the band you mention, not a video of a live performance, but a studio production, so presumably they had a hand in the overall mix, and the vocals are well up in that mix, so it might be that they would not agree with you either!
