DOWN UNDER (1983)
This song by the Austrailian group, Men at Work, has become emblematic of the great 80s rock era. Great tune.
WHEN I THINK OF YOU (1986)
This is probably my favorite Janet Jackson song, and clearly one of her best videos ever. Like her brother Michael Jackson, she helped usher in a period where stylized group dancing was the rage.
SAY YOU'LL BE THERE (1996)
Though critics like to say that The Spice Girls' debut single Wannabe is the signature tune, I believe this tune is their best.
There are just so many Eminem hits to choose from, but this song is very poignant - a conversation a dad has with his baby girl about growing up, making mistakes, and being your best. Powerful!
