Python Script to tweet last.fm scrobbles


(Jeremy Woodburn) #1

A silly conceit, but fun. The script is pretty simple (read: I’m an unsophisticated programmer), but it works. Because it hooks into last.fm, anything you scrobble (Roon, Spotify, iTunes, your player of choice) shows up.

I run it manually right now, but it could be cron’d.
