What is that japanese anime song!?!?!?!?

Ok, singaporeans would be more likely to know this song, because i watched this show on mediacorp's kids central 3 or 4 years ago. it was either a gundam seed destiny song,inuyasha song, ultraman song, I HAVE NO IDEA. ok the song is in japanese. it starts out as a few piano like notes then it picks up into a techno beat and the male singer starts, his voice is not deep, its kinda melodious, the chorus goses something like , karaku meh ku so ku meh... i have no idea if you understand, but i really want to hear that song, im sure the cartoon is a japanese anime, and its very likely to be one about robots or some other type of cartoons, PLEASE HELP ME, ITS IN MY HEAD
