How Do DJs Make Remixes

Question

When a DJ remixes another DJ’s song, how do they do it? Specifically, how do they remove certain sounds and instrumentals. Do they reach out to the original DJ and ask for their FL Studio files or whatever program they used?

Answer 1

I would assume if it’s an official collab, they receive the stems (individual track files). If not, just like in hiphop they just sample the track in a way. I think this is how it might work.
