Now I'll build out the music recommendation app step by step. Let me start with the login and authentication system.

I've built the login and survey screens. Now let me move to the emotion analysis input system.

Now let me create the final recommendation display screen:

I've built your music recommendation app with a complete user flow: login → genre survey → emotion analysis → personalized recommendations.

The app features a modern dark theme with rose/pink accent colors, smooth transitions between screens, and emotion-based song recommendations. Each screen has polished UI with gradient buttons, interactive elements (like the intensity slider), and feedback animations. Users can like songs, play previews, and see a summary of their selections. The entire flow is client-side and ready to use—just click through to see it in action!

Now let me read the component files to understand the current design:

Now I'll redesign the app with a modern, native mobile app aesthetic. I'll transform it into a more polished and app-like experience with improved navigation, better visual hierarchy, and smoother interactions.

I've completely redesigned your app to have a modern, native mobile app aesthetic with a fresh indigo-to-pink color palette. The key improvements include better visual hierarchy with progress indicators, smoother animations, improved spacing and typography, and a more polished card-based layout throughout. All screens now feel cohesive with consistent button styling, better feedback animations, and a professional app-like experience that's ready for deployment.
