If your idea of World Music is that of pious songs played on folk instruments, then you need to take a listen to this compilation. It's fun, fresh, and modern, whilst still retaining the variety and charm you'd expect if you were trawling the world for material. The 'rock' in the title is perhaps a little misleading, but this CD covers pop, rap, and an Iron Butterfly cover, so there's plenty to entertain people of all ages. Possibly the best Rough Guide CD I've heard so far.
