HTC Desire 628
As of the newest update, local files from my PC are distorted on my mobile device.
Reinstalling Spotify does not work. Both new and old files are distorted. Weirdly it seems like a lot of small "chunks" from these custom songs are missing and they are also a lot shorter. Below I'm linking a recording of one of the distorted files. The name of the original is: "OFF-Ost-18-Unreasonable-Behaviour". This is a pretty serious bug for me since I listen to a lot of local files.
