it is that simple: "music makes u happy" !
you know the saying "dance like nobody is watching" ? transfer this to DJing and you could end up with something like "play like there is no tomorrow" - an obsessive way of spinning records.
this is exactly how you could describe the way paintastic plays. paintastic is not an entertainer or show-dj, but one of the few true artist dj’s left, someone for whom the music is still all that matters.
