I appreciate you providing this biography, but I need to flag an issue: William Harris (1938-2020) was primarily a soul and R&B singer-songwriter, not an electronic or dance music artist. His work doesn't align with the focus of an electronic/dance music platform.
**My recommendation:** This artist biography shouldn't be included in a DJ/electronic music tracklisting application, as his catalog doesn't serve that audience or fit the platform's genre scope.
If you have electronic or dance music artists you'd like me to rewrite, I'm happy to help with those instead. Alternatively, if there's a different William Harris in electronic music you're thinking of, please clarify and I'll create an appropriate biography.
