Wu-Tang's stunt is a reaction to your perspective on art — to reclaim some of the novelty eradicated by the commoditization of music.
Edit/addition: Honestly, I could have much more respect for this project, if Wu-Tang made it only accessible to homeless people, or only to prisoners, but effectively, they make it only accessible to the riches. I really do like the Wu-Tang Clan, but I am really not impressed by this stunt.
