I'll create a basic Spotify clone that sources music from YouTube and plays it for users. We'll use Next.js with the App Router, and integrate with the YouTube Data API for searching videos and the YouTube Player API for playing audio.

Let's start by creating the main components of our application:

This is a basic implementation of a Spotify clone that sources music from YouTube. Here's what each component does:

1. page.tsx: The main page component that renders the Search, Playlist, and Player components.
2. Search.tsx: Allows users to search for songs. It sends requests to our API route, which in turn queries the YouTube Data API.
3. Playlist.tsx: A simple component to display the user's playlist (currently just a placeholder).
4. Player.tsx: Uses the YouTube Player API to play audio from YouTube videos. It includes play/pause functionality and displays the current song.
5. api/search/route.ts: An API route that handles search requests by querying the YouTube Data API.

To make this work, you'll need to:

1. Set up a YouTube API key and add it to your environment variables as YOUTUBE_API_KEY.

2. Install the necessary dependencies:

   npm install @types/youtube
3. Implement state management (e.g., using React Context or a state management library) to share the playlist and current song between components.
4. Enhance the Playlist component to actually add songs from search results and play them when clicked.
5. Improve error handling and add loading states.
6. Style the components to more closely resemble Spotify's design.

Remember that playing full songs from YouTube might violate YouTube's terms of service. For a production app, you'd need to ensure you have the right to use the content or consider integrating with a licensed music streaming service.

Let's debug and fix the issue with the search results and music playback. We'll need to make some changes to ensure the search results are displayed and the selected songs can be played.

Let's make the necessary changes to fix these issues:

These changes should fix the issues with search results and music playback. Here's a summary of what we've done:

1. Updated the Search component to display search results and allow adding songs to the playlist.
2. Modified the Playlist component to show the actual playlist and allow playing songs from it.
3. Enhanced the Player component to play the selected song and handle next/previous song functionality.
4. Updated the main page component to manage the state (playlist and current song) and connect all the components.

Now the app should work as follows:

1. Users can search for songs, and the results will be displayed.
2. Users can add songs to the playlist from the search results.
3. Users can play songs from the playlist.
4. The player at the bottom will show the currently playing song and allow for play/pause and next/previous song controls.

Make sure you have the YouTube API key set up correctly in your environment variables. If you're still experiencing issues, please let me know, and we can further debug the problem.
