However, I have just come across a fascinating article by Evelyn Cash about actually using music as a meditative support (or object).
Here's how it works:
I found myself able to watch my mind as I listened to the music. Certain tracks would bring up certain emotions or thoughts and I could use my meditation as a way to observe this process and watch how my mind reacted to the stimulus. In many ways, this is no different from sitting with slight knee pain or with a dog barking outside. The pain or the barking may irritate you but the point of meditation is to watch that irritation and see that it isn't you and will eventually pass away. I found that music had much the same effect. A track that I recognized would come on and I could watch my reaction to it and note: "recognition," another track might come on that I didn't like and I could just note: "aversion" then watch how my mood or even my body reacted. So the music became less of a distraction and more of a tool and an object of meditation.I would recommend this only for experienced meditators. But it really is an intriguing notion isn't it?
I also would recommend that you read the entire article quoted above. It's not very long and it gives a focused description of how the author views this exercise.
