You can start a queue from your collection screen in the app (just tap-and-hold on the albums or tracks you want to add).
Or, tap on the queue button on the album you’d like to add (you’ll find the queue button on albums and tracks in your collection just under the album cover).
To add a track, tap “…” next to the track in the tracklist.
Once you’ve made a queue, you can edit it in the new queue view.
You can swipe to remove tracks you don’t want, or drag-and-drop to re-order them.
Having trouble adding a song to a queue?
You won’t see the “add to queue” option if you’re not logged in, or if you’re trying to add a track or album that you don’t own.
