Nine Inch Nails iPhone App rejected by Apple

Trent Reznor of Nine Inch Nails announced few days back via his Twitter account, 'Apple rejects the NIN iPhone update because it contains objectionable content. The objectionable content referenced is "The Downward Spiral."' The initial NIN Access iPhone app garnered much fanfare (Wired article, Guardian article) and was approved by Apple. The update has been rejected due to an album reference. If Nine Inch Nails is having problems with censorship and approval what kind of problems are you having with the iPhone app approval process?
