There have been people who wanted to know more details about their songs (i.e. it's local play count, what's DRM, etc). There's an easy way to do this.

• Put your software into collection -- music -- songs view
• Right-click on that little bar that runs across the top of the song listing (the one with 'song', 'song artist', etc)
• Choose 'choose columns'
• You are given plenty of choices on what other information about your songs you want (photo)
