Dunno a thing about 'current songs.' All I listen to are Oldies stations, for 1950's through 60's music. Plus ballroom dance music!

Lots of anti Vietnam music:
Country Joe and the Fish "Whoopee, We're all Gonna Die",
Peter, Paul and Mary: "Blowin' In the Wind" "Down by the Riverside (Ain't Gonna Study War No More)" and "If I Had a Hammer."
Crosby Still and Nash, "Wooden Ships:

And other songs of the time:
Dion, "Abraham, Martin and John"
Creedence Clearwater Revival, "Bad Moon Rising" (the election of Nixon, how did they know?!)

Then there were all the songs on LDS and acid trips, plus all the environmental songs, with John Denver leading that movement.
