Having Johnny Cash, one of the greatest singer-songwriters of all time, want to cover your song, that's something that matters to me..."
Yup... Every month it matters to you when you pick up that huge royalty paycheck because Johnny Cash sang your song. It's essentially keeping Reznor in the lifestyle that he's become accustomed to.
Right. I remember an interview with some member of Deep Purple to this day he still gets 5 figure residuals for just one song.
Take a guess what that song is?
