## Idea

Rebuild an Album from One Song
When a local track has no usable metadata, share it from a music player to identify it and repair tags for related files in the same album.

## Product concept

Some tracks in a local music library are left with garbled filenames or missing album information after being imported from an older device. While playing one of those tracks in a music player, the user shares it with the app, sending a short audio clip, the file duration, and its folder location rather than uploading the entire library. The app uses the clip to find candidate tracks, then combines duration, track order within the folder, and cover-art clues to suggest possible albums. It displays the title, artist, year, and lower-confidence fields separately, so users can confirm each one or leave existing tags unchanged. Once one song is confirmed, the app shows other tracks in the same folder that may belong to that album. Users select the files to update, preview the fields that will be filled in or replaced, then create a backup and write the tags back locally. Tracks with uncertain matches remain in a review queue. The first version supports common audio formats stored on the user’s device, focused on identifying one track and repairing a group. It never silently overwrites low-confidence matches or forces an unrecognized song into a popular release.

## Why now (backed by facts)

A September 13 post on r/androidapps says AutomaTag now often fails to find music metadata and requires more manual entry, and asks for an alternative for tagging local music. The comments indicate that no mature solution yet offers reliable matching and updating of local music metadata when an exact artist/title lookup fails, with less manual re-entry and clear review of uncertain matches. This is a single-post observation of user friction, not evidence of a broader trend or market size.

## Source context

Theme: Alternatives to AutomaTag
Trigger Reddit single-post demand observation: r/androidapps — Any recommendations for an alternative to AutomaTag?

This is one observation bounded by its publication and capture times. It is not evidence of market size or a broad trend and only explains “why now.”

## Sources

- Any recommendations for an alternative to AutomaTag? (https://www.reddit.com/r/androidapps/comments/1wfhrfu/[redacted]/)

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
