Theres very few things in life that stop me dead in my tracks. I'm talking about the stop whatever it is you're doing and ignore whoever you're talking to kind of "stop".
The Chain by Fleetwood Mac is one of those things.
The entire song is amazing but the last minute and a half is to me, one of the most powerful sounds I have ever heard. To this day, I get chills everytime I hear John Mcvie's bass kick in around that 3 minute mark...time just stops.
