Only two tracks to test your system, forever!

"Telegraph Road" -- Dire Straits

"Anesthetize" -- Porcupine Tree

"Blackest Eyes" -- Porcupine Tree

(I get chills everything I hear Steven Wilson’s whispered backtrack in the first verse, "It’s so erotic when your makeup runs.")

"Coil" and "Heir Apparent" -- Opeth

More than two songs, I know....sorry!

Dee Dee Bridgewater A Tribute to Horace Silver, Permit me to introduce you to yourself.

This is a great track to test your system because of the overall clarity. Meet the Mets fight song by Da Stadium Organist. Impress your friends with this. It’s pretty cool because you feel like you’re really in a ball park.

Also one world one prayer by the Wailers. A lot of the other responses had good suggestions too.

The concept of a test song is tricky. I have certain songs that I consider torture tracks for a vinyl rig (Slim Gaillard - Jump Session - 78rpm) and other songs that I feel like run the gamut of a full spectrum sound (Radiohead - Pulk-Pull). These can reveal the health of my system after a change.

On the other side of the coin are those songs you know so well that any change in soundstage or presence can be detected. Dinah Washington - Blue Skies (33rpm 10" Jam Session - Mono) and Red Allen / Coleman Hawkins - Summertime (12" - Stereo) are my goto's in that department.

Finally, as some have mentioned here, songs to show off your system to others. I have totally given up on this concept - bring whatever crap you want and I'll play it. My musical passions of the week (Teenage Jesus and the Jerks, anybody?) just turn others off.
