The sample here is from "U Don't Have to Call" by Usher, starting at about the 53 second mark.
This track samples Kacey Musgrave's "Golden Hour", starting at the beginning of the track with lots and lots of stretching, echo, and distortion.
Here, the only sample is from a video of Bjork explaining how televisions work.
Caroline Polachek's "So Hot You're Hurting My Feelings" is so good that there's no possible way I improved it. But it was a fun track to make. Sample starts at about 57 seconds.
I sampled Billie Eilish's "When the party's over", which I'm sure has been done to death.
