Agree with leemaze. And I think this relates to mood. Sometimes you have to be in the mood in order to be moved. Sometimes you have to have the right setting to be in the mood.
Others have recommended chemicals. I've never used the chemical they were referring to. Not moralizing, my chemical of choice is probably far more dangerous, I just don't need another bad habit. But, I find that a little Scotch or whatever it is you like can help with the mood. I think it depends on the individual's response to alcohol. If it works the other way, by all means avoid it. I find that too much alcohol is detrimental.
Not suggesting the OP develop a bad habit, just saying, get in the mood. Relax. Stop listening to your speakers. Stop analyzing.
Another thing to consider trying. Think of specific music that has moved you in the past whether it is tapping your foot, dancing, crying, escaping/drifting away or goosebumps. Write them down in a list. Organize them by the effect they have on you. Then set the mood, however you have to do it, make sure your cousin is nowhere around, sit down and listen.
If you sit down to make that list and can't.....then you need to listen to more music and fewer systems.
