I don't know what country you're in, but none of that is played on current Top 40 radio in the USA. 1980s hits are played on oldies or old school radio stations. So unless you listen to Top 40, I wouldn't expect you to know singers/rappers/bands that are popular now. Most of the Top 20 now is usually hip hop artists. Migos, Childish Gambino, Kendrick Lamar, Drake, & Cardi B are probably the most popular rappers at the moment. Then a few singers & bands like Ariana Grande, Rihanna, Beyoncé, Bruno Mars, or Maroon 5 and maybe 1 or 2 country acts, plus whatever DJ Khaled puts out.
