I recently came to my attention the convenience that queueing a playlist would hold. This way if you want to continue the song or songs you are on and have queued, you can with the click of a button queue a CD to your lineup. This feature would be held under the three "dot"s top right of mobile devices that allows you to view info on an entire record
( ADD "Queue Album" somewhere along the mix of: "add to playlist", "star", "share", "go to artist")

We're closing out this idea as it's now possible to add albums to queues. To do so, just click the three dots on mobile/right click on desktop on an album and select 'Add to queue'
It's not possible to add Playlists to queues, but a similar idea has been suggested here: https://community.spotify.com/t5/Live-Ideas/Queue-Add-complete-Playlists-to-the-Queue/idi-p/1242182. If we have any further info, we'll add it to this thread.
