First song to "Blow You Away"...

Very recently, Mary Gauthier "Falling out of love"

Metallica, Black Album- Enter sandman. Mind blowing

double shot (of my baby's love) the swingin' medallions or peter rabbit by dj and the runaways.....can't recall which was first and second

I Am The Walrus - Beatles

Very tough time for me when I heard it on Boston radio as a kid and it made me think that there were others in worse shape than I was in at the time so I think that helped.

The opening chords haunt me to this day.

Melancholy Man by 'The Moody Blues'
Dont ask me why,but the first time I heard this just a few years ago, I was literally frozen with tingles up my spine to my brain.
I felt like running into the street and screaming like a madman..I 'am' serious.
I dont know why,it was never a hit for them or stuck out as one of their better songs,but it sure blew me away like no other song I have ever heard.
Now when I listen to it I think "was I psycho that day?"
