It's interesting, but I'm apparently not the only one who feels this way. Ten years ago when the church had a mixture of old and new music, nicely arranged, I sang up a storm along with everyone else. There was some great music, very uplifting and exciting, and I'd love to have that experience again. Now many or most of the folks in the church are singing in an unenthusiastic way. By the time the fourth repetition of the lyrics is sung, the choir is on its own and the congregation isn't singing at all, just kind of mumbling along and hoping they can sit down soon. The only time they wake up is when there's a performance by some professional gospel singer who knows how to bring it. So I'm not the only one who finds herself unable to concentrate on worship with this music; the rest of the congregation is annoyed too.
All you'll care about in Heaven is about worshipping God - and if that's singing old time hymns, then belt it out with vigor, and if all that comes to mind is this new stuff, then sing it with gusto - but the point of worship is supposed to be God centered, not self-centeredness.
No need for insults. I was just kidding; lighten up. I bet that when we're really in heaven the singing will be like nothing we've heard on this earth. Probably it will be most like the more ecstatic passages of Handel, who, as he wrote "Messiah," said tearfully that he could see heaven.
I read about Daniel dancing "with all his might" for God and think the music in heaven is going to be unstoppable, better-than-we-can-currently-imagine joyful music, next-level Earth Wind & Fire jams of eternal funky praise.
