Music's been shown to have therapeutic benefits for years, so I don't think it's surprising that it's firing up brain cells all over the place, motor, immune systems, or otherwise.
They don't say what music they used in their studies, so I'm assuming my Zeppelin is good, right?
And I love my iPod but sometimes working the damn clickwheel when your fingers don't want to cooperate can be frustrating!
