So that's only some of the list. You might find this site very handy at some point.
If you have headphones/speakers, then you should be hearing "Bless the Fall - Higinia." I'd consider it one of my favorite songs. That's right, I love screamo.
If you hear silence, then go to the bottom and find the play button. If it's not there, then that means your computer is missing some plug-in. Probably Quicktime or Windows Media.
