"Planet Rock" by Afrika Bambaataa was made with a synthesizer and is notably recognized for its electronic production.
Step-by-step explanation:
The song that was made with a synthesizer, also known as a keyboard instrument, is "Planet Rock" by Afrika Bambaataa. This track is a foundational piece of hip-hop and electro history and prominently features the sound of the iconic Roland TR-808 drum machine and other synthesizers, which were innovative in the early 1980s.
