{
  "from": "beta-tune.mp3",
  "to": "Chill/beta-tune.mp3"
}

ed music mv beta-tune.mp3 Chill
ed music mv "night drive" Focus/Deep
ed music mv Chill/beta-tune.mp3 ""

A track is resolved by trying its exact relative path first, then by a case-insensitive substring match against every track's path and title. A query that matches more than one exits 3 and lists up to five of them rather than guessing:

$ ed music mv e Chill
error: e matches 2 tracks
hint: beta-tune.mp3, Focus/delta-loop.mp3

A query matching nothing exits 3 with no track matching <query>. A destination folder that does not exist exits 3. A file already sitting at the destination, including the case where the track is already in that folder, exits 1 with <path> is already there; nothing is overwritten.

The file keeps its name across the move. Favourites are repointed at the new path, and ed posts a renamed message to the running player so the currently playing track survives being moved out from under it.
