'Worship' music

Maybe I'm the only one with this problem, but do you ever find that when listening to a song that used to move your heart when it declared how awesome God is...just doesn't do it for you anymore?
And rather than being okay with that, you try to manufacture this emotional response, because if you get all emotional then you really mean it...

That's what I'm struggling with. What really bugs me, though, is that I know that approach to worship music (or anything God-related in general) is in fact not God worship, but self worship. I get so caught in how I feel, and what I'm doing, and if I do this what does it mean about me, when the whole time God is demanding that I forsake myself and get lost in His awesomeness. A particular song may speak very specifically about my life for a time, but Jesus is forever speaking.
