# Add background music

Every faceless video can have music under the voiceover. Let Robopost choose it, or upload your own tracks to a
**BGM bucket** (BGM means background music) and pick that bucket in your video series.

**You need:** MP3 files you have the right to use (up to 50 MB each), and the **Admin** or **Manage AI Assets** right.

## Create a BGM bucket

1. Click **Content → AI Assets** ([open it](https://dash.robopost.app/ai-assets)) and click **Manage** on **BGM Buckets**. From a video series,
   you can also click **Manage Background Musics** under **Background Music**.
2. Click **New BGM Bucket**.
3. Enter a **Bucket Name**, such as "Upbeat" or "Calm piano."
4. Click **Select Audio Files** and upload one or more MP3 files.
5. Click **Create BGM Bucket**.

## Use your music in a video series

1. Open the series (**Series Settings** in its **⋮** menu) or create a new one.
2. Make sure **Background Music** is switched on.
3. In the **Background Music** list, pick your bucket.
4. Click **Update** (or **Create**).

Each new video gets one track picked at random from the bucket, so a bucket with several tracks gives your videos
variety. The same list appears in **Blog to Video** and in an automation's video settings.

## Let Robopost choose, or turn music off

- Choose **Automatically select BGM** in the **Background Music** list and Robopost picks music for each video.
- Switch **Background Music** off for videos with the voiceover only.

## Make the music louder or softer

In the series, click **Show advanced settings**. Under **Advanced audio settings**:

| Setting | Range | Default |
| --- | --- | --- |
| **Background Music Volume** | 0.05 to 0.4 | 0.17 |
| **Narration Volume** | 0.6 to 1.8 | 1.2 |

Lower the music or raise the narration if the voice is hard to hear.

## Edit or delete a bucket

Open **Content → AI Assets → BGM Buckets → Manage** ([open it](https://dash.robopost.app/bgm-buckets)) and click **Edit** on the bucket. Click
**Play Sample** to listen, add tracks or remove them with their trash button, and click **Update BGM Bucket**. To
remove the whole bucket, open the **⋮** menu on its card and click **Delete** (or click the trash button on its page),
then confirm.
