Playing music

I am running Windows 7 64bits throught a netgear 3700. I have a movie file and a music file being shared across the network over ethernet cable. I go through file manager and can play a movie, When I try the same thing with music, It doesn’t play. The mp3’s show up but nothing happens when I select them. Can anyone help. I just installed the WDTVLIVEPLUS and am still figuring it out.

Can someone head me in the right direction?
