One interesting phenomenon often overlooked in the careers of famous musicians like Britney Spears is that they might have achieved even greater success if they had not passed on songs that ultimately became major hits for other artists. Indeed, this is no random occurrence. Several top music stars have turned down songs that could have catapulted their careers or amplified their existing success. A notable example is Prince’s decision not to fully release “Nothing Compares 2 U,” a song he penned himself. Sinead O’Connor later recorded the track, transforming it into one of the most globally recognized songs ever.
