Well since MJ is known as the King of Soul (yes, wiki it) (at least 1 of them) then I must put Dangerous at age 9 I bought.
Then, yrs and yrs later, when my awareness grew I discovered Stevie Wonder and bought the 4-CD pack @ age 21?
After that I realized I needed something deeper and bought Barry White CD age 26. Finally onto Earth, Wind, and Fire then at last Marvin Gaye several months ago.
