Some contemporary Catholic music is very good such as John Michael Talbott. It seems the traditional music is out the door- while the middle age to older croud prefers the "gather" (The worst song is taste and see), type music- Most younger Catholics now want the evangelical fundamentalist rock music.
Taste and See! I know that song well! I would have to say though the worst is One Bread One Body. There's the line "One Cup of blessing which WE bless." Not God Blessing the cup, but WE. Ok that drives me nuts.
