It's told almost as if th character were narrating it, but some thoughts are portrayed as free indirect discourse. Let me see if I can find an example.
From one of my own stories...
The corners of her lips turned upwards as she sang, the last vestiges of sleep finally departing as her eyes snapped open in realization. It was a familiar song! With practiced ease, Thaliá rose to her feet without aid from her bound arms, her toes already tapping the rhythm. Pillows were kicked aside by fuzzy pink slippers as they glided into the center of the small cell, bringing with them the bouncy young woman.
"-he works his hands to the bone/ to give her money every payday," She sang to herself, her voice growing strong and melodic; there had been plenty of time to develop natural talent these last fifteen years. The words formed in her mind seconds before they sounded from the radio and rolled off her tongue in perfect accord. "But she wants more dinero just to stay at home-"
Her shoulders were a little sore. An attempt was made to rotate them, quickly deemed futile, and ignored in favour of the dance. Thaliá was slowly consumed by the music, swaying sensually in time with the beat - well, as sensually as one could sway while in an overly-confining straitjacket. Maybe they would let her take it off for a few minutes today and let her stretch out a bit. Hadn't it been a few weeks? It would have to be under close supervision, naturally - one could never be too careful.
There are some instances where I have characters express direct thoughts, so I tend to interchange the two as the situation warrants, similar to what is shown in your example.
