When you play a track, an album, playlist, etc. it pushes it into the queue of the currently selected zone. If you want to play that queue somewhere else you must transfer. This why simply pausing, selecting another zone, and hitting play ends up playing something else. It’s because you’ve changed the queue.
Now, to answer your question directly… You need to select your zone before you push anything into the queue. For example, Select your zone, Select your album, hit Play on the album (don’t hit the play button at the bottom of the screen). This will push that album into the queue, replacing what’s there, on the currently selected zone and the queue will start to play.
I hope that description helps. Here’s the KB article about selecting zones.
