Single Track that's worth the price of Admission


In another thread I commented on some resurrected analog gear that has me enjoying my old LP's.  Great fun for sure.  So given this Christmas season I pulled out some old albums.  One included a 1975 Vienna Choir Boys under the direction of Hans Gillesberger.  The last song on the album was one I had never heard or recalled from the past-- "Pueri concinite".  Now I only understood a few words, but it really did not matter.  This was one of those songs that sent chills up your spine, over and over again.  Angelic, arresting, I can't quite pick the word.  Thanks be to God above I was able to enjoy this and I never tossed my vinyl!

So here's the question.  What albums or CD's have you enjoyed where one single cut was worth the cost of admission?

@twoleftears  thanks for the link-beautiful!

@ebm  in a bit of a scroogish mood?  Come on now.

@millercarbon  thanks for the suggestion.  You won't be upset if I get the sacd or gold cd version will you!?
There was an old Englishman fuzztone who was asked if he knew the way to Lower Tuttenham. The old man thought a minute, scratched his beard, and said, "Well sir, I do know where it is. But if I was you I wouldn't start from here."
@millercarbon  Thanks for pointing that out--sadly no.  Maybe I ought to spring for the LP set.  Just not sure if my analogue rig is "worthy."  Perhaps it is given the amount of enjoyment I have had as of late.
