Do you know of any Modern Nursery Rhymes?

Do you know of any modern western nursery rhymes? By modern I mean created this century, or even in the last 30 years of the last century. I have not heard of any new rhymes, just re-imaginings or updates of old ones. The ones I know about have words changed or new music or a brought back into favour because of new teaching methods. Not that I am a connoisseur of nursery rhymes, but I did start to wonder about them a rhyme was used as a plot device in a book I was reading.

Have nursery rhymes been replaced by the children's song from a branded entertainer such as The Wiggles or Barney the Dinosaur? Are these songs our modern nursery rhymes? Will they be passed down through generations like the ones created before or will they be replaced by the next big children's entertainment thing?  I suppose it is just a reflection of the change in society in the western world combined with technology and global economics. The empires are no longer physical land masses but information and culture.

But back to traditional nursery rhymes. I discovered this great website that gives you the historical origins of some English nursery rhymes. Fascinating. Like Grimm's Fairy Tales there should be some violence warnings on the label. If you keep with this model of creating nursery rhymes from actual political and social events, it would be interesting to see what would be created from The Gulf War in 1990 or the Second Sudanese Civil War from 1988 - 2003. Or would the focus be on The Kardashians or the death of Michael Jackson? What would these rhymes teach our children?
