listen for something

I want you to listen to me for a moment.

But I should listen for such a plan, he decided.

I listen for anyone else behind me, but hear nothing.

The truth is, I could listen to him for hours.

Now listen to me, for all your life is worth.

He continued to listen for another sound like the first.

So perhaps some will listen to me, if only for a space.

I listen for a bit to hear if anyone's going to answer the door.

They did not listen to him for a long time, of course.

You can also listen to music for 12 hours and 30 minutes.
