Nice music (uncomplcated with steady rithms) that we like usually calms us down and help us to focus on the task.
I'm also nearing 30 but I still perfer listening to music over silence. But it is true that my taste for music has changed a bit. Instead of "wild" music that I listened in my youth I now prefer more calm music. I do still listen to some more "energetic" music from time to time but rarely so "wild" as in my youth.
