Whenever I'm driving and there's a song on the radio that has a police siren-like noise, there's a brief instant of panic. It's totally a Pavlovian response type situation, one in which I (luckily) don't end up drooling.
So, I was thinking… and here's an idea that anyone writing the next hit "radio" song can steal. It's 3 steps:
1) Create a hit song and sprinkle some choice words throughout the song that you know will never be able to be played on to the radio
2) Create a "radio edit" version that has some background sirens added.
3) Imagine people having a similar response as me and laugh about it.
