Favorite song to demo or test drive speakers?

Dave Matthews - Grey Blue Eyes
Whitney Houston - Exhale (Shoop Shoop)
Quincy Jones - Body Heat
Queen - Bohemian Rhapsody
Dave Brubeck - Blue Rondo a la Turk

Bobby Hackett. “String Of Pearls.” Sides 1, Then Side 2. Tests everything I need to know.

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.
