I still use last.fm. Been continously scrobbling since 2004. I also export my last.fm and Spotify listening history every now and again just in case. I plan to one day make a timeline of my listens overlayed on top of world and personal events.

I made friends I still have by browsing people who had a compatible music taste to me and then reaching out to chat.

That would be an amazing app to journal your listening history like that with Spotify on the same phone
