From what I've seen so far on this thread, what is missing from this conversation entirely is a discussion about who worship is intended for. Our English "worship" is used to translate the Hebrew and Greek verbs meaning to bow or prostrate oneself, especially before a superior. Worship is an opportunity to humble oneself before the Almighty, and while we benefit from this tremendously, worship is ultimately for God, not for us.
Imagine, if you will, a friend or spouse or whomever deciding to throw a huge party for you (birthday, graduation, whatever). That's exciting. But if you show up and the person who threw the party clearly decided to play the music they like, prepare the food they like, serve their favorite kind of cake...then who is the party really for?
Worship is not for the worshipper, no matter how much it benefits us. It is for the one we worship. Since this is the case, then the focus in our worship should be on doing what pleases Him, not what pleases us. And what pleases Him? It is not a certain form, speed, or decible in our music. It is unity of hearts and minds in full and loving submission to Him. Since He never told us that fast music is preferable to slow, or loud to soft, or instrumental to vocal, then we should not be unable and unwilling to worship in styles that are not to our liking. Whether we prefer it or not is quite beside the point.
Instead, let us gladly join with our brothers and sisters in Christ, lifting our voices, minds, and hearts to Him in unison...the way HE likes it. That's what counts.
