Songs that make me go "ahhhhh"

Everyone has their favorite songs, but there are some songs that give me a physical, almost visceral reaction. These go beyond being mere "favorites"; hearing them become necessary to my happiness in life, even if I just listen to them once every year or so. These songs are so important to me that I could literally listen to them over and over again for hours and not get tired. I did exactly that when I was a kid, much to my mother's consternation. I would play the same song over and over and over, getting the same thrill every time and discovering new facets of the recording in each listening. I considered this part of my "training in progress" at the time; I wanted to be a record producer. Fuck that, I wanted to be Brian Wilson or Phil Spector but without the mental illness and bad hair. I didn't get to be a record producer and I've struggled with mental illness, but I've got really nice hair...;-)
Now, on to my list, in no particular order:

Wolves, Lower - REM

that's all I can think of at the moment.....what are yours?
