The issue of music crashing a hard disk drive was a genuine problem. Since I later specialized in hard drives, I can confirm that every manufacturer faced this issue as multimedia laptops became more common and we transitioned to higher areal densities. To state the obvious, we shrank the tracks every time to achieve larger capacities. We were doubling capacities every nine to twelve months when we first introduced MR, GMR, and PMR heads. The hard drive industry employs incredible control theory experts due to the requirement of keeping a head on track. Personal opinion, which I probably should research, but I believe that one of the densest concentrations of Ph.D.s in leading edge control theory could be found within the hard disk drive industry. Amazing things happen when you're trying to fly nanometers off the disc in a track that is maybe 100 nanometers wide at the time.
By 2010ish, as part of our development suite, we actually played music through the speakers to identify these types of issues. The origin of this practice actually came from the ODMs in Taiwan. Therefore, Janet Jackson was not the standard qualification song we used. Instead, it was popular hits from the Chinese pop market. There were also Western songs within the suite, but I remember our team blasting Chinese pop songs at full volume on multimedia laptops.
Laptop development began moving heavily to Taiwan in the mid nineties. By the time the early two thousands arrived, there was a massive amount of competence in Taiwan regarding chassis design engineering. As time progressed, every American PC company continued to outsource development to Taiwan and eventually to China. As development was outsourced, the ODMs would work with suppliers because we wanted to present solutions to the OEMs that were free of issues.
EDIT: By the way, it wasn't necessarily a blue-screen crash. I'm not saying that that couldn't happen, but generally what we did is we had the throughput test that we were run on the hard drives. Then we would go blast the music full bore and there were certain bandwidth requirements that we needed to get out of the hard disk drive. So to add some more details behind this, I would describe it as a performance issue and the blue screen issue was relatively minor. However, this was a number of years ago and I don't remember the exact percentages.
