The "Influence or Coincidence, Inspiration or Plagiarism" Thread

Having listening to the new Mechina album Bellum Interruptum, I realized the first minute of its opening track sounds practically similar to that of the RichaadEB/Cristina Vee cover of "Bad Apple!!" When that first verse hits, I almost feel like singing "Ever on and on, I continue circling, with nothing but my hate and the carousel of agony..."

If you listen closely to the "na-na na-na, na-na na-na" hook throughout this Falling in Reverse song, do you hear anything familiar?

It's "Elmo's World"! I swear I can hear Elmo singing "Elmo's World" in my mind every time that hook comes on. That's gotta be a coincidence! See the first 30 seconds of this video:

Small fact about me that I once thought was embarrassing but I now have the guts to say here: When I was a small kid 20 years ago, singing along to that show's theme song, I kept singing "Elmo's Squirrel" instead of "Elmo's World". My parents were a little confused, thinking "Elmo has a pet squirrel?!"

Check the riff that appears at 15:25 in the Morpheus Descends YouTube clip & compare it with the riff that arrives at 1:55 in Neuropath's "Rectal Pulpation:

"Rectal Pulpation" was the first song I ever wrote for Neuropath back in 1993 & the Morpheus Descends track was released in 1994. We didn't release a studio recording of our track until the start of 1995 though so it must be pure coincidence, despite the riffs being almost exactly the same.

Why does the "again and again and again" part of this Architects song sounds so much like part of the chorus of this Chainsmokers song?! Surely that has to be a coincidence, right? RIGHT???
