YouTube Embed Curation
Music Time Machine uses YouTube's official embed player. The site does not host music files, provide downloads, or copy audio. Its value comes from selecting, organizing, and explaining songs by year and region.
Preferred Video Sources
When adding a song, the first choice is an official music video, official audio, artist channel, label channel, or a stable broadcaster upload. Older songs can be difficult because official uploads may not exist or may be blocked in some regions. In those cases, the archive favors a source that is playable, clearly labeled, and close to the original recording or a recognized performance.
- Official music video or official audio when available.
- Artist, label, broadcaster, or verified archival channels when official uploads are unavailable.
- Stable videos that allow embedding and can be loaded through the YouTube player.
- Clear title and artist information so visitors know what they are hearing.
Why Videos Sometimes Change
YouTube availability is controlled by rights holders and uploaders. A video that works today may later be removed, blocked by region, disabled for embedding, or replaced by a better official upload. Music Time Machine treats those changes as normal maintenance rather than a failure of the archive.
The player includes a broken video report path so visitors can identify a problem entry. Helpful reports include the year, region, artist, title, and what happened during playback. That lets the archive replace the ID without changing the surrounding year context.
What The Site Adds Beyond Embeds
A page that only embeds videos can be thin. Music Time Machine is designed to avoid that by adding year navigation, region comparison, decade notes, an editorial policy, region guides, and update history. The songs are not presented as isolated clips. They are part of a listening map where each year can be compared across countries.
The archive also records limitations openly. It does not claim to be an official chart, and it does not claim ownership over music or videos. It provides context and a better way to discover what a period sounded like.
Replacement Rules
When a video must be replaced, the replacement should preserve the same song whenever possible. If no stable source exists, a nearby representative track may be selected only when it improves the listening experience and fits the year. Duplicate video IDs within the same local playlist are avoided because they reduce discovery value.
This practical approach is especially important for older Korean, Japanese, and Brazilian songs. Availability varies by rights holder and region, so maintenance is part of responsible curation.
