The verse vocal melody to Leo Sayer's signature 70s soft rock ballad, When I Need Love (released February 1977) bears a strong resemblance to the chorus vocal melody to Leonard Cohen's folk song Famous Blue Raincoat (released 1971). The intro/outro vocal melody to Elton John and Gary Osborne's pop hit Little Jeannie (released May 1,1980) also seems to take inspiration from Famous Blue Raincoat (i.e "You stepped into my life from a bad dream [...]"). Thanks to Ian R. (@77BlueJays) for suggesting this comparison!

Kungs vs Cookin' on 3 Burners song This Girl (released February 19, 2016, which is a remix of the latter's original version) resembles several earlier soul/pop tracks including The Style Council's My Ever Changing Moods (released 1984), Classics IV's songs Spooky (released October 1967, and covered by related group Atlanta Rhythm Section in 1979) and Stormy (released 1968), and even Electric Light Orchestra's Evil Woman (released October 1975).
Singer-songwriter Dan Fogelberg's hit Heart Hotels (released 1980) seems to borrow it's verse vocal melody and piano intro/arrangement from America's hit Daisy Jane (released July, 1975). Oh, and Daisy Jane was from America's album Hearts.
While X Ambassadors' hit Renegades (released March 3, 2015) mines the same folksy/jamboree territory as the Lumineers and Mumford and Sons, it's chord changes are reminiscent of British rock group Sniff 'n' the Tears' Driver's Seat (released 1979).

The chorus vocal melody to American duo Timeflies' song Worse Things than Love featuring Natalie La Rose (to be released: September 18, 2015) echoes the verse vocal melody from Toto's 80s chart-topper Africa (released May 10, 1982) from the Grammy-winning album Toto IV. Compare the lines, Worse Things than Love: "Take a chance with me tonight, I know you feel it so do I", and Africa: "I hear the drums echoing tonight, but she hears only whispers of some quiet conversation."
