Meditation CD

Today in Kinokuniya, I bought a Meditation CD. I had several cds on meditation and do not find them any good so far. This time is a totally different. The CD does not give any intruction. It is just sound of beating heart and metronome at theta brainwave rate. I will try out and see if this works out better for me. Meditation is the best way to deal with stress. However it is very tedious and hard to form a habit, at least for me. Wish me luck....
