It was pointed out to me that "Stay With Me" by Sam Smith sounds like "I Won't Back Down" by Tom Petty and now I can't keep the two songs separate in my head.

These two songs have now merged together in my head: "Stay With Me" sounds like "I Won't Back Down" (originally posted on Facebook)

While Sam Smith has figured prominently in my personal internal soundtrack this year ("Latch", "[Good Thing][1]", his cover of Whitney Houston's "How Will I Know?", etc.), other than the generalized vibe of unrequited love, I didn't really feel any direct personal emotional associations with "Stay with Me" (this despite the fact that I included it on a few playlists, although it has since acquired indirect personal emotional associations….)
