I marvel at the one-hit wonders who pivot into behind-the-scenes mega success. Linda Perry is a top example. Had a minor early-90s hit with 4 Non Blondes What's Going On (title is actually "What's Up?"). Then exited the spotlight and became a songwriter and producer with major hits like Christina Aguilera's "Beautiful." Or Ashton Kutcher, who parlayed earnings from his Kelso role (plus a few forgotten movies) into an gigantic pile of money courtesy of angel investing in Twitter and more.
