Good picks
Calm, dark, easy behind a face
Bright and colourful
Moving (video backgrounds)
Screen mode
Every background page has a Screen mode button: the background fills the screen with its soundtrack playing and a small credit caption. Use it on a second monitor or a party TV, or capture the browser window in OBS (Window Capture) for a starting-soon scene.
Music that won’t get your stream muted
Every galaxy background is free for your own screens, video calls, streams and videos. Credit it like this:
