This morning, my grandfather asked my cousin and me about what music of Prince's we listened to. I didn't hear what my cousin said but I replied that I'd heard "1999", "When Doves Cry" and "Raspberry Beret". The discussion inspired me to listen to "Raspberry Beret", as it had been nearly a couple of years since I last heard it.
Coincidentally, while I was in a pub with a friend this afternoon, I heard someone whistling "Raspberry Beret". The only reason I heard the whistle above the noisy pub was because of my recent listening to the song, which likely caused my brain and hearing to separate it from all the other sounds.
Needless to say, my friend was amused when she saw me looking around to see who was whistling!
