Name some dance tunes that have clean lyrics (for children aged 3-12 years-minus the wiggles and hi 5)?

I run a children's amusement room at a leagues club and we also host birthday parties and hold discos however I've become stuck as the music cd's we have are becoming some what stale. I've asked some of the kids and parents for feedback and have got some songs, but need a bundle more.

Get a bit of Miley Cyrus, all the kids are liking her at the moment what with the whole Hannah Montana thing.

Camp Rock, Hanna Montana, Lilo and Stich, Kids Bop, Demi Lavato,
