Additionally, it points to a shared neural network involving tangible and abstract rewards. We already know that skills such as speech production use shared neural networks to those used to sing. This study shows a similar relationship, demontrating shared neural circuitry involving how our reward circuits process tangile and abstract rewards.
From a practical standpoint, this will not affect your average day-to-day listening. Just know that, when you experience an emotion while listening to music, ancient reward circuits are flooding your brain with a chemical designed to make you feel good.
