My wife and I have separate Spotify subscriptions. I've recently decided to cancel mine and switch to Tidal.

We have a few Sonos playlists that we've both added songs to over the years. When I let my Spotify subscription lapse, will we lose the playlist tracks that I've added under my own Spotify account?

Here's why I'm confused: clicking around in the playlist, I can't seem to figure out whether the "source" for a given track is my Spotify account or my wife's. It wouldn't take long to switch all of my songs to Tidal or another source, but I can't figure out how to tell whether a song is playing from my account or not.

Maybe I'm thinking about this wrong and playlist tracks aren't actually associated with a single account at all?

Thanks.
