Best songs to test speakers

Not one of my favorite types of music but Jethro Tull 'Thick As a 'Brick'. If you can find a decent/quality recording.

Thanks OP for the links. I’ve been looking for these and it’s nice to have in one list.  By the way, does anyone know if the streaming from WhatHiFi links are red book quality?

i concur. i don't love the record, but it definitely is a good system checker. 

recorded very well, and great dynamics. 

Thanks for posting the links but I concur with @br3098. 

I saw Ian Anderson' ,Jetho Trull in concert in 1973 and performing Thick as  Brick! 
If you can find it, the jazz CD The Wonderful World of Three Blind Mice. Very well produced and will give any speaker system a good workout
