"Have You Ever Seen The Rain" by Creedence Clearwater Revival. Cannot get enough of this song! It's the basis of my current favourite Genius mix.
"Behind Blue Eyes" by The Who. I tend to cycle through Who songs, and this is the current fav.
"Woodstock" by Crosby, Stills, Nash & Young. I've downloaded a ton of CSNY lately, and this is a solidly awesome song.
