Because I am an anal-retentive list nerd, I have been cataloguing my books (at Library Thing) and re-organizing my existing list of CDs (on an Excel spreadsheet).
Boy, I have a lot of books I haven't read, and I own a hell of a lot of songs that I could not, having simply read the title, for the life of me hum a bar of. Or recite any of the lyrics of. Or identify the CD they appear on.
Perhaps I've reached my saturation point.
