While MusicGen has its strengths, it also has some areas to improve.

The web app is easy to use, but it doesn’t have all the features some users might want. Some people may want more control over the music it creates.

Also, using MusicGen on your own computer requires a powerful computer. Not everyone has access to such a computer, so it could be a problem for some.

Finally, there isn’t clear guidance on how to use the music created by MusicGen in an ethical way. This is important because AI-generated content is still a new and evolving field.

  • Output quality not up to radio or streaming standards
  • Web app limited in features and control
  • Hardware requirements to run locally are high
  • No clear guidance on usage, which could lead to ethical issues
