hillsong is one of my favourites, and Shout to the lord one of the best albums, IMO. i translated alot of their songs for my p&w team, and i tell you, in here (romania, europe) was very very popular among young christians and in general pentecostal/charismatic churches!
i love all kind of christian music, but i play/sing and compose more pop, pop-rock, country, romanian folk.
is interesting to see that actually many of us have played music in the church sometimes along.
