Is Last.fm Scrobbler for YouTube™ safe?

Low risk

Last.fm Scrobbler for YouTube embeds a Last.fm API secret and uses it to sign Last.fm account and scrobble requests.

The extension source contains a hardcoded Last.fm API key and secret, and it uses them to generate signatures for authentication, now-playing, and scrobble calls. When a user connects Last.fm or submits a YouTube track, it sends artist, track, timestamp, and session details in requests to Last.fm endpoints.
