## What this tool does
Set title, artist and album plus embed cover art into an MP3 — audio stays bit-exact, no re-encoding.

## Typical user problems
- Podcast hosts and music players show "Unknown Artist" with a gray placeholder because the MP3's ID3 tags are missing or stale. The text tags are rewritten as ID3v2.3 and your JPG/PNG is embedded as official front-cover art — the audio stream itself is stream-copied, so not a single sample is re-encoded.
