I have been using Last FM for over 10 years now – a couple of students of mine from 2007 clued me into it and I haven’t really left. There was one year where I didn’t record any listening stats of my music, mostly because it was too difficult to do it (I was using a PSP as my MP3 player most of the time). Now with streaming music it’s super easy to just let it keep track of what you’re hearing and generate some great data about your music habits. Here’s last week’s profile of my listening.
