This version of Hotel California is what I usually tell people, it's mixed masterfully.

But what do I personally use? The Rain Formerly Known As Purple from the Risk of Rain 2 soundtrack has great bass and high pitched electric guitars, allowing me to check both ends of the frequency response spectrum whether there's something wrong.

This one is probably very controversial, but I use Perfect by Ed Sheeran to check male vocals. If he sounds too harsh here, then I know the headphones are too harsh for me to daily drive.

I usually just pick out a track from Porter Robinson's Nurture to check out female vocals. It's not actually a woman singing, but it's a male voice pitched high and I really like the album 😤. Same as before, if it sounds uncomfortable on this, I would not daily drive them. I pick whatever track I'm feeling at that moment, but I guess if you had to pick one, Unfold would be my choice.

So those are the 4 tracks I use to test things, mostly because I'm super comfortable with them and they cover all of what I listen to
