This application of deep learning would apply to music suitable for playing DDR/ITG/Stepmania/Stepmaniax/PIU etc.; essentially music gaming:
Most music that would be reasonably fun to play falls within 110-240BPM and runs between 2.5 and 7 minutes long. At 110BPM, a song with a coded 110BPM, but a true BPM of 110.001 will drift by roughly 2ms. Music games are predicated on timing precision down to 15ms as a minimum. I, myself, hit notes within a rough range of 6ms at my best (and I’m barely top 100 in the world).
