Fetching cover art sends music title/metadata to last.fm, is violation of user privacy
Fetching cover art from last.fm is enabled by default. Perhaps it can be asked at first launch (like VLC asks for internet access to fetch metadata). Rhythmbox is default on a lot of hardcore FOSS distros like Fedora (whome I will also send this to) and the "fetch cover art" operation is essentially happening on the servers of a private enterprise (last.fm owned by Paramount Global). Please migrate this to the pertinent section if it isn't considered an "issue".
