in the trailer for this movie ( i uploaded the vob trailer and Bender might post is later) theres this song played during the later half of the trailer and i can't figure out the name of the song or who is singing

i checked the listings at http://www.filmmusic.com/trailers and they dont seem to match to this song

heres a sample directly taken from the trailer

i really like this track, i sort of dig singers who have this "lazy" way of singing...hehehe
