"Crazy Kids" was never really released as a single tho.
"Crazy Kids f/ will.i.am" and "Crazy Kids f/ Juicy J" are different to "Crazy Kids".
When will Ke$ha release the second single from Warrior? Instead of "C'Mon", the SMASH Top 30 promo single and a remix of an album track that managed to crack the Top 40? Only Legend $, tbh.
