Turns out that Amazon digitized all of the music I have ever bought from them, including an Eminem CD from back in 2003, including the records, everything. I lost the Eminem CD a decade ago but it turns out I can still listen to it on Amazon. This is insane. I have no idea they were doing this. The list is like a trip through all the stages of my music-listening life.
They need to publicize this shit more widely because people are unaware. Or maybe only I was unaware.
