It is well known that music can have an impact on learning. Parents and teachers will argue that it distracts from learning, but there is a significant body of evidence which suggests otherwise, although you should read the small print. This link is a good start.

I have yet to find a play list for a Jazzed up German Foo Fighting Explorer, so that leaves me more confused than when I started reading the research. The more you learn, the less you know.
