Need empirical proof that you're listening to the same old artists over and over on music discovery site Last.fm? LastGraph, a slick little API app coded by Andrew Godwin, takes your Last.fm username and models it into revealing timeline graphs. Check out your overall listening frequency, and an eye-popping multi-colour artist history timeline. The big caveat is that LastGraph must, for now, institute hold queues for data-gathering and timeline rendering. If you can keep your browser open for a bit, however, it's a neat way to pull more useful data from your Last.fm profile.
