Aphex Twin was doing that 20 years ago.
Richard D James Album: Corn Mouth contains the loading noise from the attribute block of the loading screen from Sabre Wulf by Ultimate. A short tone can be heard after the attribute block. Matt Westcott suggests that this tone was generated by Keysoft’s tape copying program, The Key, in which case the game was a pirated copy!
Richard D James Album: Peek 824545201 starts with loading noise that seems to be a Speedlock-protected header block from Starstrike 3D by Realtime Software. (The filename bytes spell STARSTRIKE RND, but I’m not aware of any version of the game that’s protected with Speedlock.) There is further loading noise throughout the track , presumably from the same source. PEEK is a Spectrum BASIC keyword that retrieves a byte from memory, but the number in the title is not a valid memory address.
