While precious little has been revealed about Radiohead's success with the donation–suggested model, Nine Inch Nails' recent experiment has proven quite successful. Despite no marketing and no label, the donation–suggested 36–track album netted the artist a stunning $1,619,420 US.
The album can be purchased, completely DRM–free in both MP3 and lossless formats as well as CD and a $300.00 deluxe vinyl option. You can also download some of the album for free. The details can be found here.
