I have been on since the Audioscrobbler days, it could be over 10 years now. 82000 scrobbles. In the early days I still listened to a lot on CD, and it got nothing from mp3 players, but I still racked up the listens from mp3s on my computer, and later when I used that as a CD player hooked up to speakers. Really came into its own when I got my first phone with mp3 and internet. The top listens is interesting, some are really outdated now. I can’t get it to work with Spotify for some reason.
It would be amazing for kids to have always had it set up for every device and chronicle their lives through it. You can filter down into each song and find out the exact first listen for example, or find top songs per year.
