The intro to Ed Sheeran's Shape of You (released January 6, 2017) is very similar to the intro to Sia's Cheap Thrills (released February 11, 2016). Both feature a marimba-sounding synth playing staccato quarter note triplets for each chord. In terms of chord structure, Shape of You (in the key of E) follows a vi-ii-IV-V (or minor 6, minor 2, 4, 5) progression, while Cheap Thrills (in the key of A) follows a vi-IV-I-V (or minor 6, 4, 1, 5) progression. Shape of You is also slightly reminiscent of TLC's No Scrubs (released January 23, 1999), which is in the key of B (really G# harmonic minor), and follows a ii-vi-V/vi-vi (or minor 2, minor 6, dominant chord of the 6, minor 6). In particular, the scansion of the verse vocal melody is similar. [h/t to A. Zucker for suggesting this one!]
The intro/chorus piano melody to Flo Rida's My House (released October 15, 2015) owes a musical debt to the intro/bass melody to the Four Tops chestnut It's the Same Old Song (released July 9, 1965), while My House's chord changes are similar to those found in Curtis Mayfield and the Impressions' People Get Ready (also released in 1965). Allegedly, writer Lamont Dozier created Same Old Song's progression by reversing the changes to his preceding Tops' hit, I Can't Help Myself (Sugar Pie Honey Bunch).
American singer-songwriter Meghan Trainor's track Dear Future Husband (released September 9, 2014) is patterned directly after Dion DiMucci's doo-wop classic Runaround Sue (released September 1961). Similarities include: spoken intro over whole note strummed chords, tempo (80 bpm), background vocal parts (same male group vocal "ahh" glissando at the breaks and "hey" accents during the verses), production/arrangement (e.g. handclaps, saxophone part, bass line, drum beat, etc.), and same classic 50s chord progression (I-vi-IV-V or 1-minor 6-4-5), keys (half step apart--Runaround Sue in D major, Dear Future Husband in C# major).
The arpeggiated synth intro to Maroon 5's dance-pop single Love Somebody (released May 14, 2013) is reminiscent of the arpeggiated synth intro to the Eurythmics' Here Comes the Rain Again (released January 16, 1984). Both songs feature similar sixteenth-note patterns only a half-step apart (though chord progressions, bpms, and keys for the two songs are substantially different).
