This is a (work-in-progrss) re-implementation of a desktop application for making visualizations of last.fm scrobbling data.
Scrobbling Timeline Comparison - Compare you and another user's scrobbles side-by-side to copy theirs to your account
Scrobble missing album tracks - Find short (under 30 seconds) tracks in your scrobbled albums to fill the missing short tracks that many audio players do not scrobble automatically
