Chris: My default player (totem in Ubuntu) played it fine, but when I tried to load it into Audacity (to confirm my suspicion that the right channel is louder than the left), it went berserk. However, once I renamed the file to end in .wav instead of .mp3, Audacity was perfectly happy with it (and did indeed confirm said suspicion). Perhaps your player will play it too if you rename it.
I'm sure it will, most players go by the name rather than the contents to determine the type. But this is not the point here. It should be in mp3 format
