Illogical

Are auditory hallucinations a symptom of hyperthermia? It is super hot here, and the air conditioner at work has picked today to finally conk out for good (given the way the building management works, we can maybe expect it to be fixed by October). So I have to do some errands, which means getting in my car that has been sitting in the sun all day, and is thus somehow even hotter than the office. And I'm flipping around the radio, and three different stations are all playing Supertramp at the same time. Three! And three different songs, no less. So I'm thinking heat stroke, because there is no other possible reason why that should be happening in 2009, is there?
