Answer:
“Stereo hearts” can be considered as a piece of poetry because song lyrics can be considered as modern poetry. Its structure is similar to that of a poetry and it uses poetic techniques, too.
The first poetic technique used is metaphor. “My heart’s a stereo” is a metaphorical statement where the writer has likened his heart to a stereo which is a completely different thing.
Another poetic technique used is hyperbole. “50 pound boom box” is an exaggeration because there is no such boom box as heavy as that weight.
Another poetic techniques is rhyme. “Make me your radio. And turn me up when you feel low” uses rhyme in the ends of its lines.
