Poetry in worship?

Have you ever used or seen spoken work used in worship service? Not readings from Psalms or Proverbs but poetry like these clips. I just clicked on them surfing and was blown away.

I have never seen that before. Not for me. I found it pretentious and self-absorbed.

If that first dude is so upset by being on the road then he should find a different line of work. I only watched half of the second clip, and couldn't take it anymore.

the first one I saw was this dude Taylor Mali:

great rant imo, funny and truthful.

one dude Saul Williams, wooo! I don't know what the heck he's talking about but it sure sounds good :)

ceric the entertain does a funny bit on the cliches and pretentiousness of it all.
