Siri "Play Album..." only playing one song

I never really used Siri on my Apple TVs for music playback much in the past, but recently have started using it more in the last few months since moving from a local iTunes library to Apple Music. But I have noticed that whenever I try to ask Siri to play an album (i.e "Play the Album OK Computer by Radiohead") the music will start (with the first song on the album) but stops right after that one song plays.

I have also noticed this same behaviour when trying to play playlists from my Library (only plays the first song).

Is this expected behaviour or is this a bug?

Ideas?

Cheers!
