No, this is not about iTunes selling 200 million songs.
It’s about me having listened to every song in my iTunes playlist at work at least once.
That is, as of today at 1:52 PM, 3708 songs, that can be played without repeating for 10 days, 22 hours, 7 minutes and 57 seconds (give or take). For those who care, that’s 17.36 GB worth of music.
