Kidz Bop 16 includes "Hoedown Throwdown," "The Climb," "Circus Circus," "Boom Boom Pow," and 12 other songs. (And what I like about Kidz Bop is that these songs are all cleaned-up — no curse words or suggestive words.)
The Halloween Deluxe CD includes "Monster Mash," "The Addams Family," "Nightmare on My Street," and "Who Let the Ghosts Out." 
16 songs total on this CD, too!
