A/B Testing (Very) Small Bookshelf Speakers

Hello, just for fun am going to be doing an A/B speaker comparison, nearfield listening, ranking some small bookshelf speakers. Just planning it out now and was thinking of comparing 3-4 songs per speaker, from different genres which I primarily listen to. Now considering Classic Rock, Progressive Rock, Punk Rock and "Grab-Bag" which could be pretty much anything that would be good for this type of thing. Any song suggestions? Thanks!!

Right now, the speakers that may be a part of the test are:

Proac Super Tablette,
Snell Type M,
Ascend Acoustics Sierra,
Solus SC-06,
Focal Chorus 806V,
Monitor Audio Silver S2,
Ruark Sabre,
Clements 801di
