Well, so phhht! I was reading the local or federated timeline I forget which and I clicked on some podcast and was listening to that on my phone here, but then I accidentally pressed back or something, and it went back into Mastodon and that timeline refreshed to the beginning I guess, and now I can't find it again, and the little embedded Chrome or whatever that was actually playing it doesn't seem to expose its history anywhere, so it's just gone forever!
I suppose this is good practice in not clinging.
And possibly in noticing the titles of podcasts that one is listening to.
