From Born a Crime, by Trevor Noah:
One day Bongani came to me and said, “You know what would make a lot of money? Instead of copying whole albums, why don’t you put the best tracks of different albums onto one CD, because people only wanna hear the songs they like.” That sounded like a great idea, so I started making mix CDs. Those sold well. Then a few weeks later Bongani came back and said, “Can you make the tracks fade into one another so the music moves from track one to track two without a break and the beat carries on? It’ll be like a DJ playing a complete set the whole night.” That sounded like a great idea, too. I downloaded a program called BPM, “beats per minute.” It had a graphical interface that looked like two vinyl records side by side, and I could mix and fade between songs, basically everything a DJ can do live. I started making party CDs, and those started selling like hotcakes, too.
Business was booming. By matric I was balling, making 500 rand a week. To put that in perspective, there are maids in South Africa who still earn less than that today. It’s a shit salary if you’re trying to support a family, but as a sixteen-year-old living at home with no real expenses, I was living the dream.
