If you say "I don't know; I deleted the Apple-provided Purchased Song playlist," well, you can use this hint to create a new one. It's just a Smart Playlist that will show all your purchase activity (based on matching Protected AAC songs). That's why I left "I don't know" off the poll as a valid response.
And if you happen to be off the top of the charts, and feel like sharing, feel free to add your actual unit purchase quantity in the comments. I admit to a strange curiosity about who may be the "most addicted purchaser" amongst the community. I'm pretty sure it's not me, with 454 songs in three years (which is about seven CDs a year, which is roughly how often I used to buy actual CDs).
