Mac only: Just when you thought you couldn't possibly need more statistics on your music listening habits, free Mac app LastHistory comes along and graphically analyzes your Last.fm logs, over time, while also integrating with other Mac apps like iPhoto and iCal.

Last.fm has some really great statistics, but it lacks the ability to show change over time—which is where LastHistory comes in. Not only do you get a cool graphical representation of your listening history, organized by time, tracks, and genre, but you can search, highlight old playlists (that you might not even have around anymore), and even play music directly in the app. What's even better is that it can grab events from iCal and iPhoto, showing you exactly what you were listening to while you were jaunting around Italy three years ago. There are a lot of different dimensions to this app, and if you're a music junkie who loves the statistics that Last.fm gives you, you'll love how LastHistory extends that even further.

LastHistory is a free download, Mac only.
