But every time I see it, I remember a really odd side effect that I had while on a mood stabilizer (not sure which -- could well have been valproic acid, the same drug referenced in the article). A few days into taking the drug, I found that music that I knew well sounded different; specifically, it sounded like it was being played back too fast, as if you were playing 44.1khz audio at 48khz. I initially figured I screwed something up on my machine, but tested myself with various other songs on other devices, and every one of them was too sharp.
This continued for several days and was the primary reason I ended up switching to a different medication; I don't have absolute pitch but I have very finely tuned relative pitch and that's not something I would be happy about giving up. Discontinuing the meds fixed it within a day, but I've always wondered exactly why that happened. Very odd.
