Ah, for messages I have a cop siren. It's hilarious since whenever I'm at a party it freaks people out.
California Love by Tupac and Dr Dre and my text alert is a clip of Will Ferrell's office guy character saying "I'M THIS CLOSE TO RAPING YOU" my phone's usually on silent though.

It is "Bounce" from System of a Down! I can hear it even if I am miiiiiiiiiiiiiiiiiiiles away from my mobile! loool!
i've just changed mine. its the part of Pendulum // Propane Nightmares. the bit where the best kicks in
