I have finally cleared my "never played" playlist in iTunes. It won't last long - I am constantly receiving new music from hip-hop artists and ripping old records from my collection - but this is a minor victory. At one point, I think I had 10 or 12 days worth of music to which I had not listened. Technically, it's a bit of a cheat, too - I'm excluding my radio archives and multiple versions of a song (if I get instrumental, clean, and dirty versions, I only listen to one) - but throw me a bone. I win!
