George Michael. I had a Wham album back in the day, but never listened to any of his solo stuff really. Never listened after the 80s. Had no idea how much music he released...no clue. Also had no idea he wrote every song he's ever recorded on his albums (except standards). He was very talented, but I had no idea and missed out on all that. Some of these songs are so catchy. He sure knew how to write a pop hook that's for sure.
