What song is this from?

[Jeffryyyy]

this is the off-topic section is it not?!?!
& the {YTID} shit is not working

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
