What's the most "mid" Metallica song?

What is the most mid aka middle of the road aka unremarkable song Metallica has? Not BAD, because that makes a song remarkable somewhat.

Example, you could say Slither is a "bad" Metallica song but that makes it something, not unremarakble and mid.

You may find Ronnie to be "mid" but musically it's pretty out there for them and a new sound for them so there's something to talk about at least.

Then you get my choice: Murder One

That song is so unremarkable and bland but not bad either it's just there, very mid.

I hope you understand what this thread is going for, drop your song choice below.
