Thanks for taking time to post all those "best" of links. It’ll be interesting to see what they include.

FWIW - Steely Dan's "Do It Again" is listed to test detail under the best tracks for testing treble category.

It changes as I get boarded with some songs hearing them over and over again.

Right now I use Dean Peer Travelogue and Think... it's all good CDs.

I like to hear how the bass guitar sounds and backing instruments to see if the tone is correct, the impact of the bass and how the backing instruments are layered and separated keeping the right decay and overall tone.  I don't want to hear bongos and drums sound like cardboard boxes but I want to hear the bong of the skin flexing.

IMO using poorly recorded CDs is just that a poor recording so I don't find that helpful in evaluating a system or component.

Happy Listening. 
Best songs:

1.  Heart is a Drum by Beck
2.  Give Life Back to Music by Daft Punk
3.   Water Mellon Man by Herbie Hancock
4.  4ware by Deadmau5
5.  Like Someone in Love by Diana Krawl
6.  Nasty by Vincent Ingala

NOTE:  These are great songs to test for bass extension and sound
              stage.  Try to listen to these on TIDAL in MQA.
Not one of my favorite types of music but Jethro Tull 'Thick As a 'Brick'. If you can find a decent/quality recording.
