is it just me or are there more people that experience this??

since i was a kid, ive ALWAYS listened to music, mostly to the radio. But those same songs, after listening to them a couple times, got imprinted in my brain. im taking straight up listening to them on my head when trying to go to sleep, focus, or even randomly. Honestly its kinda cool, but after a while it becomes really annoying. Am i the only one that has this happening to themselves???
