The chorus vocal melodies and chord progressions for Break Your Plans (released May 9, 2014) and Please Don't Leave Me (released January 31, 2009) are very similar. Both BYP in the key of C , and PDLM in the key of C#--only a half-step higher--follow a classic I-V-vi-IV progression (e.g. Let It Be, Don't Stop Believin', Let It Go, etc.), and both chorus vocal melodies go from a whole note on the root to the second step.

The chorus to Demi Lovato's single This Is Me (released June 6, 2008) from the Disney Camp Rock movie, echoes both the chorus chord progression and chorus vocal melody of Avril Lavigne's My Happy Ending (released July 7, 2004). Similarities include: key--only a half-step apart (TIM: C#, MHE: D), chord progression (both songs follow a IV-I-V or 4-1-5, and IV-I-V-vi or 4-1-5-6 pattern), vocal melody (compare the lines TIM: "No more hiding who I want to be"; with MHE: "All this time you were pretendin'"), alt-pop/pop-rock production (distorted power chords and drum patterns that emphasize eighth notes for the first and third beats of each measure i.e. ONE-AND, two, THREE-AND, four ).
The chorus vocal melody to Paramore's funk-pop track Ain't It Fun (released February 4, 2014) is similar to the chorus vocal melody to Swing Out Sister's late '80s hit Breakout (released October 3, 1986). Both chorus vocal melodies are built on major pentatonic scales with common notes (AIF in E major pentatonic: E F# G# B C; and Breakout in A major pentatonic: A B C# E F#). Compare the lines: AIF ("Ain't it fun, liv-in' in the real world" B-C#-E-B-B-G#-F#-E, with Breakout ("Don't start to ask, and now you've found a way to make it last" C#-E-F#-B-B-E-F#-G#-B-G#-A-G#-E-E)
Ain't It Fun (released February 4, 2014) by Tennessee alt pop band Paramore is similar rhythmically to several late 80s/early 90s "New Jack Swing" era hits including Every Little Step by Bobby Brown (released March 9, 1989), Nasty by Janet Jackson (released April 15, 1986), and 1988's Joy and Pain by Rob Base/DJ EZ Rock--featuring the original Maze sample, as well as to Life Is A Highway by Tom Cochrane (released September 20, 1991), and Steely Dan's Kid Charlemagne (released May 1976). Ain't It Fun is built on a common funk/R&B groove whose origins can be traced back to the legendary session drummer Bernard Purdie, and subsequently, producers Teddy Riley and Jimmy Jam.

Ain't It Fun's verse vocal melody for the line "What are you gonna do when the world don't open up 'round you?" parallels the verse vocal melody to the line "What'll you do when you get lonely?" in Eric Clapton's Layla.
