Change in the url string

Hi, I've noticed that the source URL has changed from ID numbers to names (strings). For instance the example above changed from https://rock.com.ar/artistas/73/ to https://rock.com.ar/artistas/luis-alberto-spinetta/, in most cases they redirects automatically to the correct one, buto I'm not sure that this happens everytime. I suggest to change the old format to the new one in order to keep consistency with the external database. Mr. Moonlight (talk) 20:21, 27 September 2023 (UTC)
