I have spotify premium. When downloading a playlist to my mac it doesn't download every song. I've reinstalled spotify, it didn't help. In the screenshot below I've created a small playlist of 44 songs, when I clicked download it said it was only downloading 42 of them. In a larger playlist it's only downloaded 132 of 267. It seems to be random, half an album will download while the other half won't. Why is this happening?
