So, I installed spotify (on 14.04) using this method. It created a spotify folder in /opt/. My faenza icon theme seems to work for almost all supported apps except for spotify. I tried changing the icons manually in the /opt/spotify/icons folder and that didn't work either.
The spotify executable's icon inside /usr/share/applications changed but whenever the app's icon appears in the launcher, it's still the original spotify logo. I even went to the root folder and tried searching for any other instances of the original logo, but couldn't find any.
Here is a screenshot of the issue:
Any help would be appreciated.
