There's a good thread on this forum on the origins of the different file formats e.g. MP3.
Apparently, when MP3 was developed in Germany, the audio engineers needed tracks to test the frequency loss vs the original recording while "tweaking" the data loss of the compressed file. Various tracks were test from the 1812 Overture, Vivaldi and other pop, metal tracks and so it goes.
There was one track that MP3 couldn't reproduce which lead to a complete overhaul of the code to what we finally have today as "MP3".
If I ever obtain this on CD, I'll be using it to test my stereo setup.
