Below is a catalogue of my favorite brainwave meditation music. For best results, use headphones.
For sleep, choose Delta brainwave CDs
For creativity, intuition, and dreaming, choose Theta brainwave CDs
For mental focus and memory, choose Beta brainwave CDs such as Brainwave Massage 2.0.
For general relaxation, choose Alpha brainwave CDs
For heightened spiritual awareness, choose Gamma or Hyper Gamma brainwave CDs or the Awakened Mind series
