def on_queue_update(update):
    if isinstance(update, fal_client.InProgress):
        for log in update.logs:
           print(log["message"])

result = fal_client.subscribe(
    "mureka/api/lyrics/extend",
    arguments={
        "lyrics": "[Verse]
     In the stormy night, I wander alone
    Lost in the rain, feeling like I have been thrown"
    },

    on_queue_update=on_queue_update,
)
print(result)
```

### JavaScript

Ensure you have the JavaScript client installed:

```bash
npm install --save @fal-ai/client
```

Then use the API client to make requests:

```javascript
import { fal } from "@fal-ai/client";

const result = await fal.subscribe("mureka/api/lyrics/extend", {
  input: {
    lyrics: "[Verse]
   In the stormy night, I wander alone
  Lost in the rain, feeling like I have been thrown"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);
```
