Heh, kinda funny. Cosmic and I have a lot in common some days and other days, we are at opposite ends of the spectrum. Today, we are in sync completely. The first song that came to mind, without even thinking about it, or reading anyone else's posts was
Prince - Purple Rain. What a great song!
My other top choice would be
Kiss - Black Diamond (from their self titled debut)
Love Reign O'er Me is one of my top fave tunes by the Who. I didn't even remember that it's the last song on Quad as I never listen to that album, just specific songs off of it. Great choice there as well Cosmic.
A couple others off the top of my head:
Kiss - Strange Ways (from Hotter Than Hell)
Kiss - War Machine (from Creatures of the Night)
Kiss - And On the 8th Day (from Lick It Up)
Metallica - The Call of Ktulu (from Ride the Lightning)
Scorpions - Still Loving You (from Love at First Sting)
Scorpions - Holiday (from Lovedrive)
Scorpions - Believe in Love (from Savage Amusement)
Scorpions - Send Me An Angel (from Crazy World)
AC/DC - Rock and Roll Ain't Noise Pollution (from Back in Black)
I better stop
Heh, kind of an interesting note that the 4 songs I picked from the Scorps are all power ballads. Great way to close out an album IMHO.
