Wiz Khalifa's See You Again (released March 17, 2015, and featuring Charlie Puth) has a similar chorus to Kevin Ross' This is My Wish (which Jordin Sparks originally recorded and released for Glade on December 9, 2013).
The chorus vocal melody for the Pixies' song Gigantic (released August 22, 1988, and featured in a recent iPhone 5S ad) is reminiscent of the chorus vocal melody to Kool and the Gang's 1983 R&B hit Joanna. Both melodies follow the same 5-2-1 progression (Gigantic in the key of G: D-A-G, and Joanna in the key of Bb: F-C-Bb), and share a similar rhythm i.e. each three-note melody starts on the second eighth note of the fourth beat (the "and" of four), followed by a longer note on the downbeat of the next measure (the "one"), and the final note on the upbeat in the same measure. Gigantic (:37) VS Joanna (1:18)
Other songs with melodies based around the fifth, second, and root degrees of the scale: the intro to Evergreen (Barbra Streisand), and the chorus to Lost In Love (Air Supply).
