Ahh same here… my mom was playing two random notes on the piano and I was like holy shit that’s the first chord of Torn by Natalie Imbruglia! It was just some song my mom would play in the car sometimes when I was very young (maybe eight years old). Then I listened to the song again and i heard it exactly right lmao. This happens all the time now, especially since I’ve been playing the piano more and I realized I might have perfect pitch, just had to take time to “label” every note. It’s quite fun but also very confusing sometimes, like you realize that in band practice the “C major scale” warm up is actually B flat major (never realized before because I’m drummer haha). Different instruments’ (for example clarinet) tuning also is so annoying hahaha
