3000 RPM/70 MPH Engine Drone

Forgive the several noob questions. I just purchased an '06 Focus as a commuter car and it's been along time since I owned a 4cyl engine. Plus, I'm a bit (ok, alot) OCD so strange noises, rattles and buzzing drives me to my xanax stash...

I've noticed that my Focus has alot of engine drone - almost a "booming" sound at around 3000 RPM. It's especially noticeable on the highway, right around 70-75 mph (my typical commute speed). This engine drone sound is far louder than any road or wind noise. It is definitely engine noise - if I put the vehicle in neutral (5 speed manual) at that speed the noise goes away instantly.

This does not seem normal to me and I'm looking for suggestions. I searched "engine drone" and found some references to the passenger side engine mount. I've checked it and it doesn't appear to be leaking, plus the car has only 59k miles on it. Help! Any comments or advice appreciated.
