Eh. Music without words is kind of daunting.
I find the reliance on lyrics to propel a song often causes you to lose track of what makes the actual music good. Songs can be good just for the tune, and while I generally prefer a singer to be present, they don't have to be singing anything meaningful. It's just the sound of a vocalist to add tone color.
Then again, I'm usually pretty bad at hearing lyrics correctly, so understandably I place a much greater emphasis on the other parts of the song.
