What the...??

Why am I able to download my own mp3 for free right here:

http://beemp3.com/index.php?q=margaret+stowe&st=artist

Here's where it's downloading it from:
http://chrwradio.com/lma/2003/Margaret%20Stowe%20-%20Things%20I%20Do/Margaret%20Stowe%20-%20Moody%20Blue.mp3

People can share this free link with their friends by sending them this url:
http://beemp3.com/download.php?file=3111116&song=Margaret+Stowe+-+Business+Trip

or they can embed a player in their webpage.
