I would recommend no music, no voice, no nothing. Zazen is where it's at. It's a specific posture, a specific way to sit, but other than that, it's just calm and quiet and you versus the silence of your mind. http://en.wikipedia.org/wiki/Zazen But honestly, whatever works for you. If it's music and a voice, that's fine by me. As I've talked about in the thread insom linked, there's all kinds of sects of buddhism and you would have to find what meditation style works for you. But many come back to pure zazen because it seems to work the best. As for sticking with it, just start small, 15 minutes a day. It's just sitting after all, consider it a productive nap of some sort. I do 30 minutes a day normally, sometimes it's only 20. Depends on the day.
