What a tough question! This goes more towards songs that are fun to hear endlessly, which is different than my favorite songs of all time. I’d go: 

Bob Marley’s “Trenchtown Rock”
Grateful Dead’s “Eyes of the World”
Stormzy’s “Mel Made Me Do It”
Jackson Browne’s “Doctor My Eyes”
DJ Khaled and Jay-Z’s “GOD DID,” especially since Jay-Z released the Beat segment breaking down that song as a Jay-Z track, “HOV DID.”
