On my pixel 6, I don’t know what update changed this, but you have to tap the music symbol on the lock screen to get it to ID a song. I want it to listen all the time like it used to so I can no-hassle scrobble vinyl to last.fm. Any ideas?
AFAIK it only shows the song immediately if the phone can identify it offline. It can only do that with a limited set of songs so if you listen to something less known it won’t be able to recognise it without talking to google first. When you click the music symbol on the lock screen it actually uses online services to identify what’s playing.
It used to identify all the time though, without touching the music symbol. My last.fm used to show what I listen to at the grocery store or dentist’s office for example ha
The song list gets updated from time to time. That’s the only thing that I’m aware has changed. I think you might have just gotten lucky with songs being included in the list before and now, possibly after an update to the list, are less lucky.
