If I'm writing... even a piece of a song... I write it down. If it still resonates six months down the line, a year, even five, those are the ones you put in your bag and you take to the studio. You come to realize, the ones that don't make it, they were only meant to live for that moment in your notebook or on the 4-track-and plenty of songs never get any farther than the 4-track.
