If your Sim is a shower singer, occasional guitar busker, or secret piano virtuoso, writing a song in The Sims 4 is a fantastic way to turn their talent into your family's main source of cash. Paired with the ability to license music, you can rake in hundreds of Simoleons in royalties per song daily. Or, if you're just doing it for the love of music, you can also just keep tracks under your belt for future performances.
Writing a song can be confusing because it's locked until later skill levels, presumably to protect the general public from the awkward musical attempts your Sim makes at level 1. To make things worse, writing and licensing songs are both required steps of the Musical Genius aspiration with little explanation—trying to figure out how to meet this requirement in my early Simming years made me lose my mind.
