Music for setting up speakers

Im setting up my 30yr old Martin Logan Sequel II’s. I followed some ML guidelines and it was pretty straight forward. They are 8’ apart and 8’ from me. I towed them in using a flashlight and beam reflection, it was pretty easy, same for the reflection to be sure one isnt tilted forward or backward more than the other.

I’ve been listening to some Tidal tracks and wondering what you listen to to confirm your setup is right for you.

I listened to some solo violin and cello, some folky vocals, some Led Zepp just because :0)

maybe music where instruments are easily located ect

Thanx
