Oh, great (imho, the best ) decade for music!!
I'm not going to post a lot, but these songs have defined the decade the most for me

The Bee Gees - Stayin 'Alive
Gloria Gaynor - I Will Survive
Pink Floyd - Another Brick in the Wall Part
Queen - Bohemian Rhapsody
John Lennon - Imagine
-----------
Some other great and favorite songs
The Beatles - The Long And Winding Road
Pink Floyd - Comfortably Numb
The Clash - (White Man) In Hammersmith Palais
George Harrison - My Sweet Lord
Donna Summer - I Feel Love
Kraftwerk - The Model
David Bowie - Life On Mars?
David Bowie - Heroes
Michael Jackson - Don't Stop 'Til You Get Enough
The Jacksons - Shake your body
etc.
Rolling Stones, Led Zeppelin, Marvin Gaye, Stevie Wonder ruled this decade and created great music, but it will be cunning, if I say that I am a huge fan, but I have great respect for each of them ... I think it will be a lot songs from these artists in this thread even without me.

I liked 80s music better,because popular(white) music is much better,but the 70s dance jams are supreme.Authentic dance music made by great musicians.

Disco/Funk-The ultimate master of melody and rhythm.

I go 80s 70s 60s in that order-all fantastic music
