Each emoji represents a word or set of words. This should be fairly easy to get.
I think it is
Never gonna give you up, never gonna let you down
(AKA a Rickroll)
As it has been asked in the comments below my answer and it's probably not clear for everyone how I came to my answer, here are my thoughts:
the first emoji with the arms crossed can be seen as a cross which can refer to stop, never, no, ...
the up and down arrows should be self explaining..
the second emoji with two hands showing was more a guess than knowing what it was supposed to be, but taking in the first emoji (and 4th) and the third (and 6th) I got "Never [blank] up, never [blank] down" and this highly suggests this beeing a rickroll (since the meme is rather common on the internet)
