I agree with all of what has been said the last few posts. Taking vocals out of a song does not make the song better. To me, hearing an instrumental version of a song is nothing more than a cool once-off or twice-off experience. It's cool to hear some of the instrumental nuances that aren't so clear when the vocals are there, and can help appreciate some parts more. But after that, I have no desire to revisit an instrumental of a song that has such a huge, vital piece missing.
