Which music style is this and other songs

Hi, I would like to ask which music style is this: http://www.youtube.com/watch?v=6TSuuPdthfw
Parts 0:20 – 0:50 and then 0:50 – 1:04… the part 0:50 – 1:04 sounds very similar to me, I’m sure I’ve heard it somewhere, but I don’t know which music style it is… does anybody know? And also, if you know a song which sounds same/similar, post it here too please
