 - `/play` takes a name or a URL, `/queue` shows the queue, `/volume` sets 0 to 150 percent. These need a role called **DJ**.
 - The now-playing message has buttons for playback and repeat. Buttons also check for the DJ role.
-- `/music toggle` (Manage Server) turns music on or off in a server. `/music skip`, `pause`, `resume`, `stop`, `repeat`, `remove` and `move` control playback and the queue (DJ role).
+- `/music toggle` (Manage Server) turns music on or off in a server. `/music remove` and `/music move` edit the queue (DJ role).
 - The queue and now-playing state are kept in the database, and playback can also be controlled by writing to the `music_commands` table. The hosted Velox dashboard uses this (see [Database](database.md)); you never need it, the commands above do the same.
 - Music needs a Lavalink server. Without `LAVALINK_HOST` the rest of the bot works and music does not.
