Does anyone know other rap songs that used the same sample (Stevie Wonder - Ribbon in the sky)? I looked on whosampled and can't find the song, but I'm sure I heard it used before, probably in a rap song.

Not a super helpful comment for you but I have to tell someone: I came to this sub to find the sample with an ascending synth line https://youtu.be/rDemHxmMlNI?si=61rgO7e-iUGyIZ3g in this song and your post was first and it has an ascending synth line! Not the same sample, but what are the chances
