where and how to run just dance dlc?

Hiya ive been having lots of fun with the dolphin emulator and getting my roms from here :D , all works perfect so far...Now ive been a bit confused about dlc in specific to just dance...(downloading just dance 2 , 3 and 4 :D ) , do the iso here include that? if not where to get em and how to install em on dolphin?
