So you are working with a bank? Those are the places which mostly block these kind of apps. If you are then it is a matter of time before they are on to Google music and blocking it too.
No I'm in the biomed industry. I've heard of several other major tech companies doing this as well. I've been doing this for 4 years while spotify has been blocked for 4 years. I doubt IT at my company will look into finding a way to block google anytime soon.
