I recently had this problem while using Spotfy Premium on Ubuntu 14.04
At first I thought it was my new headphone amp, but I tried a bunch things came to the following conclusion:
The crackling is not due to Spotify alone. It only occurs with my particular DAC (X-Fi Go! SB110) AND Spotify. Spotify on other computers sounds fine even with my DAC and Spotify, so it's combination of computer, audio device, and Spotify from what I can tell. I'm super confused right now.
One thing you can do is try deleting the local files and then resyncing them to your device. And/Or try completely deleting the spotty application then reinstalling. Also does this only happen on one of your devices.

There doesn't seem to be a definitive solution to this problem, from what I've seen. I'm using Spotify on an Android, Galaxy S3, and it has worked fine for over a year. All of the sudden I am getting pops and crackling in streaming and downloaded songs. Tried everything on here, and want to keep my premium subscription but will stop paying soon because the music is ruined by this problem. Am I missing something, maybe another thread?
I've had the same problem and I was going crazy because of it. I have a Toshiba (4 year old Tecra) with Win7 64bit and I am using a Bose Mini Soundlink as my external speaker (great sound, by the way...), linked via bluetooth. As I was experiencing some syncing problems, I changed some parameters, almost everywhere, including the speakers properties in windows sound config.
MacBook Air, i7, aftermarket SSD, optioned to the max; trying out Spotify Premium, and playing to Bose Spoundlink mini, via Bluetooth.Today, first time, appalling crackling; so much so I had to stop listening. Right now, 30 mins later, excellent. What did I change? Zilch.
So, I will keep an ear on this; I can listen to my music via iTunes with zero distortion, so if the problem continues, that is my option.
