lyrehc, we have a grandson who spent a year at Hillsong in Australia, and he loved it. He thought about going back, but I think he has other ideas now. He is a Youth Pastor and Worship leader in an Assembly of God church on the East Coast USA. Crisi, you are correct about the mood of the music. It definately has an effect on you, so uplifting music that encourages you in Christian living is best. That music definately puts you in a good mood! I am now playing the piano out of a book that I got by just paying the shipping and handling to Hope Publishing Company which make a really great deal on the hymn/song book. The book is "Worship and Rejoice." It was copyrighted in 2001 which I think makes it the newest book I have. I have to be honest in that I like the older books, hymns, songs better, but I am playing it for the exposure to the newer music. It is good, and my piano playing skills have improved enough so that I can enjoy playing that music now, whereas before it was a little more difficult. The book has a mix of older and newer, so it will be fine. I am now just on song 12 out of 749 songs, so I have a few to go. I just keep playing them until I have played every song in the book. Normally I play each song only once, but once in a while Carol hears a song that she likes, and she asks me to play it again, so I sometimes play that song 3 times for her. One song that comes to mind is "When I Survey the Wondrous Cross." She said that she loves the harmony in that song, so I played it several times for her.
