I always wondered what it would be like if I had a video game soundtrack, so I used MusicLM to generate with the prompt: "a video game soundtrack about a pink character with red and blue eyes, limbs, and feet with a red hat" (I'm not aloud to use key words like Kirby, or Mario). Here are the results! Sadly it's short, but maybe in the future you can have longer generations?
