## Evaluation Prompt

# Task
Using https://ai.google.dev/gemini-api/docs/music-generation, complete the following task:

Using Google Lyria, build me a Python script that generates an original instrumental music track:

1. Follow the Google Lyria documentation to authenticate and choose the simplest text-to-music API path
2. Generate 30 seconds of upbeat electronic background music for a product launch video, with no vocals
3. Save the result as output.mp3, output.wav, or output.m4a, using a format supported by the API
4. Print a confirmation message with the filename and file size when the track is saved

Use documented Google Lyria APIs only; do not generate fake or placeholder audio. 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
