My primary choices would be:
True Faith - the Alternate Faith Dub
Bizarre Love Triangle - 12" remix
Regret - Fire Island Mix
The Perfect Kiss - 12" remix
That mix of True Faith would be my all-time favorite if the throbbing percussion at the end didn't go on for so long and become a bit boring. But I'm real biased towards that mix because one of my favorite NO lyrics is TF's "I used to think that the day would never come / That my life would depend on the morning sun...." So when we got that "the mor - the mor - the mor - the mor - the mor -the morning sun," I thought the Universe was talking to me.
Love it best when NO's mixes are different from the album versions, so Regret's and BLT's mix are fantastic for me. Of course, the BLT 12" was released before the album (or I got it first) so that was my first introduction to the song and it will always be one my dearest NO songs.
What can I say about the end of the Perfect Kiss 12"? Amazing.
