what beat/song is this from...

[Jeffryyyy]

there is a part in this beat that remindes me of a older song, and i cant stop thinking about it i need help finding it out... the short part i'm talking about is the whistling after the beat grind at the 0:18 mark, you can hear it again at the 0:09 mark but its not quite the same as the 0:18 sec mark
