Only two flaws found.
First and probably the worst of the two is when you describe the song with male voice, piano as the only instrument, and slow pop love song. You think you were descriptive enough. The only part it keeps getting right is male voice. They are all fast pop full instruments over powering the song. The second thing is you cant put your chord progressions with the changes above the words where it would change. The AI isn’t intelligent enough to not say the words chorus and pre chorus and verse # in the song. Also you cant tell it when to build or just write chorus where the repeat chorus would play. With that being said i will say the app is great for beginners in the song writing field. I would like to see a beginner and advanced version. App has a lot of potential and room to grow. Not a bad app though. I will probably look for a more advanced app of the same style.
