​@tom.duffy.52 with deezer, "Add to Queue" means adding a song, album, or playlist to the end of the current playback list. This means the added item will play after the currently playing tracks or whatever is already in the queue.

When you add a song to the queue, it's added to the end of the list, meaning it will play after all the items that are currently in the queue, including your current playlist.

If you want to hear the track next, choose “Play next.”
