According to one of Trent Reznor's latest tweets, an update to the very popular and crafty Nine Inch Nails application has been rejected by Apple.

Apple rejects the NIN iPhone update because it contains objectionable content. The objectionable content referenced is "The Downward Spiral"

For any of you not familar, The Downward Spiral was Reznor's 1994 hit album that featured the popular song "Closer". It's a pretty good guess that is the song that put a halt to this update hitting the App Store. But wait one second... you can purchase this complete album including that particular song right one iTunes?!

Not much to say about this one but wow... just wow.

Update: Our good friend from WMExperts, @PhilNickinson, just sent over a link from the NIN forums where Trent Reznor has posted a bit more information on the rejection. Turns out The Downward Spiral is not even available to listen to in the updated app yet the objectionable content is The Downward Spiral... We are scratching our heads as well.
