Let's have Spotify locally save all mobile offline play history and write it to Last.fm scrobble list when you turn it back online. Even better - a Spotify play history on desktop and mobile applications that tracks all play history online or offline.
Hey everyone, Spotify Staff here. We don't have any further updates around scrobbling your tracks played offline to Last.fm, but we're keeping this status as 'Good Idea'. We'll continue to let the internal teams know this is a popular request. Thanks again for all your feedback here in the Ideas board!
