Favorite song to demo or test drive speakers?

Supertramp: "Bloody Well Right", the XTC album, "Apple Venus Part 1", Ocean Colour Scene: "The Riverboat Song"

News on an overseas Internet radio followed by whatever they played afterwards.

First song I picked: Elvis Presley - It’s Easy For You. Followed by Blue Eyes Crying In The Rain. Followed by the whole Moody Blue album.

If it couldn't play those well, I would take it straight to Goodwill. Luckily, there is nothing that does not play those well.

Zep’s Immigrant Song

I have Two favorites:
"Makin' Whoopee" by Bradford Marsali from Trio Jeepy Album
&
"Concierto de Aranjuez" by Jim Hall from Album Concierto

First sound, if a TT is up:

Sweet Child, The Pentangle
...just because it's one of the first albums I own....still 9/10, too. *S*

Otherwise:

Beat Box (Diversion One)....for the piano @ the end of it....
The Holy Egoism of Genius
....both of these: The Art of Noise

Lately.....
Cube 3.0 @ Creamfields 2019, Deadmau5
...loud, Please. *G*

I didn't say you had to agree nor like it.
