I've been meaning to write a post about music I like to listen to while programming. My main criteria is that it doesn't have words I can understand, because that triggers the language part of my brain, which makes it impossible for me to decide what to call my variable.
A full post will have to wait, but the moment, I'm really enjoying a radio station full of African music. I found it in iTunes: Radio -> International/World > Afriki Djigui Theatri. They also have a website.
It's beautiful, most of it has a nice beat, and I can't understand a word.
