I WANT MUSIC RECs! PLEASE HELP!

What GREAT MUSIC do I need to hear? Looking 20th and 21st century.

Please comment with YOUR THOUGHTS. One artist and one song from each decade. Would help if you mention the genre as well.

If you only love ONE decade of music, that's OKAY! Just answer that! 

Here goes:

1) 1910s

2) 1920s

3) 1930s

4) 1940s

5) 1950s

6) 1960s

7) 1970s

8) 1980s

9) 1990s

10) 2000s

11) 2010s

12) 2020s  

Copy and paste in your own bulletin if you want to play too. 

Hoping for different genres as well. ESPECIALLY ones I may not normally listen to!
