The music for meditation and visualisation section includes CDs with calming music to use in the background whilst meditating, or to help with visualisation practices. If you find it hard to empty your mind and clear your thoughts completely when you try and meditate, perhaps a CD might help? The music can help by giving you something to focus on beyond your worldly worries. Plus the nature of meditation music is that it tends to be light and ethereal, helping to transport you into higher realms.
If you want to work on balancing or rejuvenating your chakras, specially designed music CDs can assist your visualisation practice.
