Spotify iPhone App forgets Music Queue when switching apps on iPhone

[brettfriesen24]

When i am at work I build a long Shuffled Music Queue from my favorite playlists and as the day goes along I switch apps and pause my Spotify and then come back a while later and the Shuffle queue has started from scratch.  

This causes me to have to reset up my queue and remove the songs that I have already heard.  It would be nice if the music queue would auto-save or something so when I come back it remembered where I left off instead of simply remembering what playlist I was playing.
