Man, this is not easy. At all!
But, sentimental memories bring to mind "Ramble On." I was 15 and working at a gas station with some older guys. One guy, Jerry, is a senior in high school and had friends at Bloomsburg (a PA university). He takes me up there for my first experience, this is back in '93, of a "real" party. Beer, girls, pot, loud music, and NO COPS. I got hammered, made out with a couple girls and thought I was the man, chugged beers, and then puked.
We hit up a pizza place to get our shit together, and as I'm housing some amazing pizza on comes "Ramble On."
I'd been into Zeppelin for a few years b/c of my Dad, but the timing of this song just set it off as something epic at that point in time. I felt Paige's guitar and Plant's vocals just ripping out a good time, kind of echoing the time I had that evening. It was just different, 15 and feeling like you took another step towards being independent. Haha, what did I know!
So, the culmination of events leading to hearing that song make it stand out in my mind.
