I really love the sleep timer function! Ever since I found out Spotify now has one, I am using it. I have some trouble falling asleep and this certainly helps me to relax. I would really appreciate it if there were more times added, like 90 minutes or even 2 hours... Sometimes the 1 hour isn't enough, I am still awake but have listened for quite some time, so I pick up my phone and set it back to 60 minutes... But then I was usin my phone again, which isn't really part of my plan of falling asleep, you know.
Sorry for any grammar mistakes if there are any (there certainly are :D)
