If you download it from your computer to an MP3 player, how would it know your subscription was canceled?

I only use my MP3 player for breaks and have several different files in different genres. But, got them all from walmart.com (88 cents per), load them into a Nomad Jukebox. Walmart doesn't use the MP3 format, but rather .wma format and all have been at 128 kbps.
