New Music??? Issues with it!

On the Minecraft title screen after not clicking anything for a while, Minecraft started playing some funky music. I googled it, and found these were new tracks added in 1.7.2. Anyways i was listening to a couple of new "tunes" and at a point in time, two tunes i heard before played on top of each other. It was a mess and the music sounded weird. I recorded it with fraps and will add file below.
