I was reading an article, and it mentioned DRM limits on mp3's, and in the context that it used it it led me to believe that this is some sort of copyright that allows you to play a song only a select few times. Is this the case? If so, there is this song that I love, and whenever I aquire a copy of it, it only plays once and then never again. I can even burn it to a cd and nothing. Is this because of the DRM limits?
