In the music industry, sometimes a song becomes tangled in a game of eeny, meeny, miny, moe before it lands in the right hands. Kelly Clarkson's "Since U Been Gone" could've been Pink's had she not passed; Whitney Houston's "How Will I Know" was originally intended for Janet Jackson, and Sia originally reached out to Katy Perry for "Pretty Hurts" before it went to Beyoncé.
