I get alot of crackling noise when using Spotify in my car. Similar results using an iphone 5s and my new iphone 6. I connect to my car (Mini Cooper S 2014) using a premium bmw iphone cable. I have also tried with an original apple cable with same results. When connecting, spotify recognizes the infotainment system and i can scroll through my playlists directly on the central display.

I have temporarily switched to deezer to avoid this and everything is working fine. Deezer is just a lot worse product than spotify. So i was hoping that someone can help me fix this issue so i can go back to using Spotify.
