Agreed, I've been to lots of clubs and listened to heavy bass music most of my adult life. Launches are still indescribable and it just put an instant smile on my face and still gives me goosebumps after all these years as I wasn't even that close to the launch site (bluffs about 10 miles away): I saw the Falcon 9 launch at Vandenburg that made people think the aliens arrived [0].
