Several years ago, I mysteriously lost half of my library in iTunes. With an email to support, I was able to get most of my purchases, but as this was the pre-cloud era, DRM prevented me from getting it all back. I was told to like it or lump it. So, I lumped it. That was the last time I bought something from the iTunes Store. I started fresh, converted my purchases to MP3, re-ripped our library in Windows Media Player (complete with multiple genres reference from Wikipedia), and 739 albums later, we were back in business.
