Apparantly, what you SHOULDN'T choose is Wagner's Ride of the Valkyries (a.k.a. the helicopter song from Apocalypse Now). At least, according to the article in the
Herald Sun: Wagner 'dangerous to drivers' [15apr04].
Also on the bad list: Dies Irae from Giuseppe Verdi's Requiem, Firestarter by the Prodigy, Red Alert by Basement Jaxx, and Insomnia by Faithless.
