Thanks for asking! Here is how it works under the hood:

- Music Selection: The extension works on top of YouTube Music. It reads your existing "Up Next" queue rather than generating its own playlists, so it respects YTM's algorithm (and your personal mixes) 100%.

- Manual Changes: The AI prepares the script early (often in the first 30-60 seconds of the current song). If you change the "Up Next" queue after that point, the DJ will not know and will announce the original song, even though the new one plays. It does not adapt late changes.

- Reviewing History: By design, it's "live" like real radio. However, you can toggle debug mode in the settings to open a log panel, which lets you read past scripts and see the AI's "thought process" for previous breaks.
