song without rap?

So uhm yea..

I have to sing a song in music class..

And the good thing is I can choose the song on my own,  so it can be a ballad, pop-, rock-, anything-song.

Buuuuuuuut.

I wanna sing a kpop song... that doesn't involve rap. Cause I'm such a great rapper.. -cough-not.-cough -

Soo... does anyone have any ideas? 

 don't really care what group or genre it is..

As long as it's not too fast and not too happy and childish and whatsoever...
