According to RollingStone.com, NINE INCH NAILS mainman Trent Reznor earlier today (Tuesday, April 22) released a brand new song, titled "Discipline", to radio stations. Unlike the instrumental "Ghosts I-IV" album, which was web-released less than two months ago, the new track actually features vocals from Reznor. In addition, an April 21 post on NINE INCH NAILS' official web site, www.nin.com, reads "2 weeks!" echoing a similarly mysterious message posted in mid-February that ultimately resulted in the release of "Ghosts I-IV".NINE INCH NAILS recently launched an online film festival showcasing short films made by fans to accompany music from the new NINE INCH NAILS album, "Ghosts I IV". According to a press release, the NINE INCH NAILS channel on YouTube, which went live on March 13, is accepting submissions immediately through May 1. Music from "Ghosts I IV" is available for filmmakers through YouTube's AudioSwap channel. Submissions will be personally reviewed by Trent Reznor, who will host a festival featuring the best entries at a later date. Reznor released "Ghosts I IV" online on March 2. The two-hour collection of 36 untitled instrumental tracks was made available in various high-quality DRM-free formats at different price levels. According to a press statement, a total of 781,917 copies of the project were transacted at NIN.com in the first week of release, including paid and free downloads, plus pre-orders for physical editions of the set. The total gross earned was reported as $1,619,420. The expensive "ultra-deluxe" limited edition of "Ghosts I - IV" sold out almost instantly despite a steep $300 price tag. A digital version is available for five dollars, along with a $75 limited edition "deluxe" package. A $10 double CD version and a $39 vinyl edition was made available at U.S. retail on April 8.
