Personally I did not like the choice in music. Bungie has been building up the arrival of TTK for quite some time now, and the overall tone they used was much darker. I felt as if there was this sense of urgency on the horizon. But when I saw that commercial, I felt like I was about to play another freakin Call of Duty. The threat of Oryx has been replaced with upbeat guardians taking a stroll, who aren't enduring any type of struggle. My impression was that they were having fun. For TTK, my guardian should not come off as having fun. He should be enduring a threat that has entered the Solar System and is seeking him out for revenge. This in turn makes the experience fun for me as a player, by building tension and suspense due to this looming threat. That commercial did not do it for me.
