Totally!
There actually are "standards" (for movies, anyway) that state certain levels of audio to be on the digital recording, and the system can be calibrated to produce a certain SPL of audio through the speakers with a test noise. Assuming your speakers have a certain capability and your room is perfect and your Johnson rod and muffler bearings are in a certain state of tune, etc. etc.
Music recordings aren't bound by these guidelines and as such they cram their level on the recording all the way to the top. You might find that the loudest you can stand is somewhere between -30 and -18 on your readout there, depending on the kind of music. (very very simplified explanation, though.)
But yeah, for the real world, the plus sign on the remote means louder and the minus sign means quieter.
