ListenDB
What you actually listened to, month by month, with genres at the centre. Your history is collected quietly in the background and kept for as long as you want it.
Spotify keeps only about your last 50 plays, so this builds an archive from the day you start. Earlier listening cannot be recovered by anyone.
Your listening is private unless you choose otherwise. You can download everything held about you, or delete it, from your own page at any time.
