The song you're describing is "Take On Me" by the Norwegian pop band a-ha. It was released in 1985 and became a worldwide hit, reaching number one in many countries, including the United States, United Kingdom, and Australia. The song's distinctive intro, featuring a high-pitched vocal part and a synthesizer riff, has been widely recognized and imitated in popular culture.
