Load your iPod and pick your Genre of music.
But pick the right one.
Don't make the mistake I did by listening to an afternoon of New Wave when you had tried to upload only New Age.
It will raise your ire more than your chill factor.
When you are looking forward to 40 minutes of growing your hair to some easy-listening, don't fidget when it comes to the genre selection and accidentally upload 5 albums of A Capella Acid Jazz.
And when you have found a cable that connects your iPod to your gramophone and you are sitting in the drawing room with a glass of port, lighting your pipe and awaiting a gentle murder, make sure you have set it to Chamber Music rather than Christian Gangsta Rap.
Believe me, it's an easy mistake to make.
