Honestly a human DJ might well do what the Spotify DJ does — play a popular piece that matches the outlandish request and then transition to other music.
To torture the metaphor further - it's also a personal dj, with an audience and customer of 1. Somewhat by definition there can be no outlandish requests, certainly not "play this entire piece".
If I told the DJ at my wedding to play an album front to back, and they transitioned to Aerosmith, I'd be tapping a friend to run the music the rest of the night.
