The music need not e chosen at random, I see no benefit in that.
Here is a spectrum analysis snapshot of Burn The Witch by Radiohead, a song I might listen to any day of the week. Might as well use a real example. I do not listen to average music, I listen to specific songs.
Full spectrum, a fairly even distribution of energy with no shortage of upper mids and highs. The rms signal levels are -11 dBFS left and -8.3 dBFS right.
Same passage, but with a 12 dB/oct high-pass filter at 500 Hz. The rms signal levels have only dropped to -13.6 dBFS and -11.8 dBFS, a difference of 2.6 and 3.5 dB respectively, indicating that MF and HF energy accounts for about half of the energy of the track at that point in time.
