Lack of Pleasure and Joy
Sounds like you are looking for positive emotions from entertainment (e.g. music). That is one way to get positive emotions... not necessarily invalid but rather superficial and not lasting.

Another way to get joy is through setting challenging goals and achieving them. When you can overcome your weakness / limits, you will feel rewarded, and worthy of self-respect.

In Buddhism the challenging goal we set is Right Bodily Behavior, Right Verbal Behavior and Right Mental Behavior. When we overcome our bad habits and achieve certain level of perfection, we can truly congratulate ourselves and that gives the special type of joy. (And then the joy of Completion, which is the highest.)

But even on mundane level, you can set challenging goals, like sport, raise yourself to challenge despite pain and weakness - and then congratulate yourself. Try it, it really does work ;)
