# Music > The three things Music offers, what a pack is made of, uploading a bed of your own, and what music does to the finished video. Source: https://docs.kutly.io/settings/music/ **Music** is the bed under the narration. The setting sits in the row under the box in both modes and opens a list of three — **None**, **Music pack** and **Your own bed**. It starts on **None**. ## None The finished video has no bed under it. Your narration is the whole of its audio. ## Music pack A pack is a scored bed in two parts. The intro is the hook: it plays once from the start and is mixed louder than what comes after, so the opening of the video has something carrying it. The loop follows and repeats to the end. The preview button plays the loop rather than the intro, so the clip you audition in the picker is the bed under most of the video and not its first few seconds. Choosing **Music pack** opens the picker, and the choice lands only when you click a pack inside it. Seven instrumental beds, one per row, each with its name and a line saying what it sounds like. A search box narrows the list by name, and while a preview plays a seek bar grows inside its own row. Clicking a row picks the pack and closes the picker, and **Music** then reads the name of that bed rather than the words **Music pack**. **Screenshot to add:** The music picker: a search box reading Search packs, and under it seven rows, each a preview button, a name and a line saying what it sounds like — Cold Evidence, icy strings and procedural tension; Forgotten Archives, dust and tape hiss; Night Signal, pulsing synth; Open Frame, bright and airy; Simple Ground, warm acoustic; The Investigator, noir piano; War Room, militaristic percussion. Cold Evidence is outlined and ticked. ## Your own bed **Your own bed** takes MP3, WAV, AAC or FLAC, up to 50 MB. Drop a file and it uploads at once. **Generate**, the arrow button at the end of the settings row, is disabled while a bed is on its way up, and the slot beside it reads **Finishing music upload…** once that is the only thing it is waiting on. Your file is looped to fill the video and cut at the end of it, so a short bed repeats and a long one is trimmed. ## What music does to the finished video The bed is one audio layer under the narration, which plays at full level over it. ## What it costs Music is free. Nothing you pick here moves the figure beside **Generate**, and the [receipt](https://docs.kutly.io/settings/length-and-credits/) has no line for it.
