Wifes albums playing on my phone?

[Gazr]

When I'm listening to my premium Spotify offline it still plays my wife's albums that I've not got downloaded on my phone, how do I stop this?

[HowardMarks]

Can you explain a little more?

Are you both using the same account but on different devices?

[Gazr]

Yes same account but different devices.
Her albums are playing on mine even though I've not downloaded them on my
device and I play mine offline so shouldn't play hers
