He also had a unique plan in store for the new music’s release. According to engineer Michael Prince, his vision was to finish many of the tracks while his concerts were going in London and release them one-by-one as singles, not as a full album. It was a brilliant idea. Jackson, as always, was keenly attuned to the music industry and felt this was the ideal way to disseminate his music in the age of digital downloading. He also realized that with the publicity generated by his ongoing stay at the biggest venue in the world, the anticipation for each new song would be huge. Rather than give critics a chance to immediately dismiss his new album as a flop, he would outsmart them by having hit single after hit single, and finally, once he reached ten to twelve songs, release it as a full album.
