Sadish Piano & Violin Track by Zaytoven & Migos?
 

Song starts with a piano and a violin, slow, some lyrics I can think of are "used to... My nigga," and "money change..." And I think it's a song by Migos. Only producers I can think of is Zaytoven or south side. Please help.

The introduction starts with a piano melody, when the melody is about to end the violin/organ joins with the piano melody. I'm certain its produced by Zaytoven or South Side.
