What are your top songs that you use to evaluate a new high end purchase ?


When I bring home a piece to evaluate ( I only evaluate at home, or another household ), I have a handful of  recordings ( songs actually ) I specifically listen to ( keeping in mind warm up time / break in time ) for the new piece, as I know, and enjoy, these selections ( on CD ). Rolling Stones : Under My Thumb > Sway > Wild Horses > Can't You Hear Me Knock'in ( Maybe another or 2 ). SRV : Tin Pan Alley. Led Zep : When the Levee Breaks > Stairway To Heaven. Sarah Vaughnn : All of Me. Sheffield Drum Record > The solos. Allman Brothers ( at the Fillmore East ) One Way Out. Blind Faith : Do what you like. I estimate this about 1 1/2 hour.  At this point, I usually know if I like it. If I do not like it, I would know much sooner. Enjoy ! MrD.

As you eluded to, I think it's important to use music you like and are familiar with. The one lp I always pull out is Shawn Colvin "Steady On".
Alluded....

I don’t see the literary reference, but maybe I’m blind. 
Great choices.  I listen to the Allman Bros Little Martha and You don't love me, the Dan's Babylon Sisters and Aja, Diana Krall Live in Paris, and, although I love jazz, the only song I ever need to hear when evaluating components or speakers is Grant Green's Idle Moments.  
@maritime51,

elude …. "the appreciation of".
Grateful Dead / Reckoning Side 2
David Bowie / Hunky Dory Side 2
Bardo Pond / Dilate Side 1

I will say however that when evaluating I listen more to the overall tone, clarity, stage size, etc., throughout all the music I listen to in order to determine if it stays in the system or not.   
@slaw 

No, "alluded" is likely what you meant.  I searched up some definitions of "elude" and none come close to suggest "the appreciation of".  Here is more what they all say:

Thanks for correcting me. At least my thoughts were of the correct intention.
Here's one of my favorites: "The Unknown Soldier" from Weather Report's I Sing The Body Electric! 
Two more: "Through Metamorphic Rocks" from Tangerine Dream's Force Majeure. And "The Nile Song" from Pink Floyd's More soundtrack!
And not to neglect classical: the last movement of Mahler's First Symphony - Ozawa and the BSO on DG! The last movement of St.Saens Symphony 3 - Barenboim and the CSO on DG! Both of these will really give any system a workout dynamic-range wise. Play them LOUD!
Jazz: "It's About Time" from Miles' In A Silent Way! And "Miles Runs The Voodoo Down" from Bitches Brew!
"Crossroads" from Cream's Wheels Of Fire!
"Badge" from Cream's Goodbye!
"Lather" from Jefferson Airplane's Crown Of Creation!
Two from Procul Harum's A Salty Dog: the title track and "The Devil Came From Kansas"!
You obviously like the Stones - Monkey Man and Beast of Burden should be on your list.
The Sounds Of Silence. 
I think part of it is listening to a wide range of  different material in recording style, scale, range, dynamics and other attributes. In term of what I use, it varies, but one constant is Between the Lines- Janis Ian. I am well familiar with the recording, it has much to commend it whether or not you like the music, from spare arrangements with female voice to more elaborate production including horns, strings. The original issues were cut by RL, for what that's worth, and sound pretty much identical to a test pressing I have. But, part of the process is seeing (or hearing) where the illusion fails, or isn't as convincing. Some of this results from the source material itself, so it does make sense to use recordings that are familiar to you. 
After all of these years : Jazz at the Pawnshop, Vol. 1, SACD. Enjoy ! MrD.
Here are a few well recorded performances that have to sing in captivating fashion, or I wouldn't want the system!  Each has its "tells" for revealing the sonic influence of a system change.

Jazz:
Shelly Manne & His Men - at the Blackhawk, Vol. 1 "Summertime"
Charles Mingus - Mingus Ah Um "Goodbye Porkpie Hat"
Grant Green - Idle Moments "Idle Moments"

Classical:
Bach, Passacaglia and Fugue in C minor, BWV 582, Peter Hurford on organ
Bruckner Symph 7, Gunter Wand & NDR - "1st Movement" is telling
Debussy, Zoltan Kocsis on piano - "Images, Livre 1:  Reflets dans l'eau" 
Enrique Coria - Latin Touch "Verano Porteno"

Rock:
Beck - Odelay "Where It's At"
Neil Young - Live at Massey Hall "Old Man"
Low Reed - Magic & Loss "Power and Glory"
Pink Floyd - The Wall "Hey You"

Interesting choices listed above.  Love the music selection but not many I would use for evaluating audio equipment.  I generally look for live recordings, and trio jazz music or music with sax, piano and stand up bass.  No electronic music or rock & roll as the recordings are usually compressed.  I use piano recordings so that I can evaluate the weight of the notes, the decay, and how much wood on the piano I can hear.  Sax I want to hear if I can hear the reed vibrating, and the tone, vocals hear the air coming out of the mouth and stand up bass the wood and definition.  Once I hear all that, then I cam confident that Stevie Ray and Duane and Dickey will also sound good.

Happy Listening. 
I agree with BigKidz that a variety of "live recordings (acoustic & electric) is essential, as is songs where the notes have a lot of decay (particularly acoustic piano). Big picture wise, have some male and female vocals, while also focusing on guitar, bass, drums and keyboards. Finding something with a string quartet or a full orchestra is also a good idea. Little picture wise, any song that gives you "goosebumps" is an automatic candidate; or, any song that you pick up subtle details on headphones but not your current speakers would also be good.

Some of my recent "live" favorites are: "Fools in Love/For Your Love" - JOE JACKSON; "No More Buffalo" - JAMES MCMURTRY & "First and Repair" - MONTE MONTGOMERY.

Some of my recent "studio" favorites are: "Get Inside" - JOHNNY A; "Try, Try, Try" - ALEJANDRO ESCOVEDO; "That is Why" - JELLYFISH or anything from "Turn Of The Cards" by RENAISSANCE. I also agree with Irish_Tim that "Babylon Sisters" by STEELY DAN is an excellent choice.

Good luck and happy speaker hunting!

 
I listen to alot of compressed studio recordings because of my musical tastes. Most all live recordings and higher quality audiophile recordings sound great. I need my system to sound good on everything. I know many people who only play audiophile recordings, and although I have many, I listen to it all. What I have realized, in every case, is that I am listening to recordings, and I am fine with that. As long as I am able to " get into the music ". Enjoy ! MrD.
