I’ve been using last.fm for almost 11 years now. Primarily, I use it as a statistical database of my listening habits, or at least the portion of my listening that happens on internet connected devices / services.
Of course, last.fm is useful for more than just cataloguing your listening habits. It’s a streaming radio service, a community site for talking about music and more. For me, though, it’s always been most amusing as the place where I can go to remind myself what I was listening to 5 years ago, or which songs I’ve listened to most, or whatever. For example, I found myself wondering how many songs I listen to in a day on days when I work at home. 40 lines of Python later (including whitespace 😉 and reasonable exception handling) and I had my answer.
In a consumer society there are inevitably two kinds of slaves:
the prisoners of addiction and the prisoners of envy.
