Domain for Web Filtering

[Kaynith]

I work at a small company that allows the employees to listen to spotify and a few other music apps while they work.  However we are planning a change to the software we use to control web access.  Our current software is desktop based and installed on each machine, and I simply have to add an exclusion for the Spotify app to run.  The new web filtering will be a cloud based DNS/Proxy service, and I will need to know the domain that spotify connects to so that I can allow it internet access.  This information would be greatly appreciated by myself, and my coworkers.
