Vagueish description of song

Its a typical pop/electronic song with a regular singer and a rapping part by someone else somewhere in there, I believe it was only added recently (have they just updated the playlist within the past few weeks?)

Bad description but its all I got

NOT talking about the pitbull song

Edit: should add that the singer and rapper are both guys

Heard it again while working today and remembered the lyrics this time
