Christian Hip-Hop?

The cover story at Christianity Today asks if Christian Hip-Hop can call American church back to the gospel -- not referring to Catholics, of course. My first thought was that this cannot posibly fit into liturgy, but, to be fair, Evangelicals do not share the original meaning of the word "liturgy" anyway. I suppose that any form of art, if truly uplifting and inspirational, can be used to glorify God. Setting word to rhyme can be good for many, but never in the Eucharistic celebrations of the Mass, of course. I've often thought that a Catholic parish that is Christ-centered in the Eucharist primarily, and the other sacraments, can bear much fruit with other communal celebrations, including prayerful song -- maybe even Christian hip-hop, -- outside of the Mass. Thoughts, anyone?
