What music do you use to assess your system?


I'm looking for music that will reveal shortcomings or strengths within ones system. Lets list some of our favorite songs that have: good, fluctuating bass lines, songs that have a solid, centerd vocal, songs that are super complex with alot going on, songs that test tone, songs that test inner and micro detail, songs that test how well a speaker can convey dynamic swing, and any other aspects I didn't mention.

Of course I'm not looking for one song that covers all areas, I'm fine with one song only covering one aspect.

When listing songs, please include what we are looking for in that particular song!

Old thread... but I'll add Spoon to mix. The whole album is fantastic but the first side of Transference is a reference for me. (All Spoon albums are a must for me)

Also Sting Ten Sumners Tales.

Cannonball Adderly Something Else

Norah Jones first side of Not Too Late.

In the end well recorded large scale classical works always set the highest bar in regards to what it takes to reproduce them best.

For me in addition to that, to cover all the bases safely, I always want to test with various forms of music that includes well recorded electronic music elements just to make sure things are up too the task of delivering the goods at higher volume with this stuff as well without any noticeable rounding, breakup, distortion, limited dynamics, etc.

If those two things can be done really well chances are you are in good shape for most anything else less challenging that comes down the pipe.
I just listen and enjoy without thinking too much about how it sounds, but how it makes me feel. I'm feeling mighty fine lately.
Bach Cantatas by Le petite band .
Kurt Elling/"Man in the Air"
The one and only Stanley Turrentine / "Joyride" on Blue Note. Great sound with fabulous band throwing in everything to include the kitchen sink !
Simply mic'd vocals with accompaniment (piano is good, but acoustic guitar will do), and recordings I've made myself with a pair of good condensers and a Revox A77.
