I've had Sonos for many years. I listen almost exclusively to MP3's stored on my local NAS. A lot of my listening is podcasts, and a lot of that is longish ones like LSE lectures or college classes. I also listen to lots of audio books (again as MP3's, not commercial ones like Audible) and old-tyme radio dramas. I control all this from the Android app.
One feature that should be trivially-easy to implement is a bookmark scheme. Sometimes when I'm listening to a podcast or spoken material I want to stop and switch to music. Maybe it's time for my exercise or maybe guests are coming over. But when I'm done I want to return to my spoken-word content.where
I left off. I originally requested a bookmark feature like this back in 2010, and I just spoke to tech support a few hours ago and he said they STILL don't have a way to do this! I can't believe that in 2019 I still have to keep a pad of Post-It notes
handy for keeping track of Sonos timestamps so I can pick up where I left off! Why is this a hard problem?
