This site does exactly as the title suggests, simply choose a genre of music, create your prompt (or upload your own lyrics if you're a pro). When you are happy with the lyrics suggested just go ahead and render the song which can take up to 30 seconds. Before you know it you'll have a decent song (hopefully). Our prompt was "A song about a potato growing up and leaving home"...yep super random. If you'd like to hear what the Potato Song sounds like, give it a listen here.
