 ## Download pipeline (hard-won knowledge)
 
 - Downloads are **yt-dlp only** (the old squid.wtf/Qobuz backend was removed).
+- **iTunes store = US everywhere** (`api.js` search, `metadata.js` `lookupItunesTrackMeta` /
+  `searchItunesAlbumTracks`). Was JP-first, which localized Western artists to katakana ("DJスネイク")
+  on some tracks and kept kanji on others → the *same* artist resolved differently between downloads.
+  US-only gives one consistent name per artist and halves the download's iTunes calls. Titles come
+  from the source, so a Japanese title the user picked stays Japanese; only iTunes-derived fields
+  (album\_artist, genre, year, artwork) follow the US store.
 - **File naming:** `{NN - }Artist - Title.ext` with the release suffix stripped from the
   title (no `- Single`/`- EP`). The **album folder keeps the full album name**. Original names
   are used for folder, filename, and all main tags (artist/title/album/album\_artist) — even
