The mere idea of this is really fucked up. Listening to anything for 24-hours straight is a really bad idea, but this article claims that one individual was forced to listen to Eminem's The Eminem Show album, loudly, 24 hours a day for at least a MONTH. I guess that's better than listening to an individual song as it appears that others were forced to do over and over and over but it would still really suck. A month of "Rain Man". Oh no.
