Yes, Heechul just recently tweeted a video that showed Defcon (you know him right, he Is a korean rapper and hip hop artist) making (??) a remix or practicing his spinning skills on super junior's albums.
He also giggles a lot and boasted the super junior Bonamana album he got from Super Junior which was fully autographed (I hear jealous ELF's ... or perhaps im hearing myself) and he got a photo card of Heechul! Lucky guy~ perhaps heechul gave the album :)
Hope to hear some remixed versions of Super Junior's songs from Defcon :)
