First there was the Caffeine's replacement brainwave.
Now, after your votes here, I created a brand new brainwave for Energy and Motivation.

BEFORE you download and use this brainwave you HAVE to:

1. Read the introduction to brainwaves and brain entrainment here
2. Understand and accept the following WARNINGs!
   The following people should NOT use brain entrainment:
   > People subject to any forms of seizures or epilepsy
   > People using pacemakers
   > People suffering from cardiac arrhythmia or other heart disorders
   > People taking stimulants, psychoactive drugs, or tranquilizers
3. Read the following tips to enjoy this brainwave listening:
   a. It is important to listen to it, using stereo headphones
   b. Don't activate music-looping on your media player or your MP3 player.
   c. Adjust the volume to a comfortable level
   d. To use this session, find a quiet place. Make sure you are in a comfortable position.
   e. After starting the session, close your eyes and listen to the sound.
   Optionally, you can keep your eyes open and use this as a "background" while doing your activities.
   f. If you are using this session for motivational purposes, it could be beneficial to visualize your goals while the session is playing.
4. Don't keep it on too long, however, since too much energy can be a bad thing.

So, after all these info, you can download from here the 10 minutes duration brainwave file that I called "The Brain's Energy Drink" because of its feature to keep you in an energizing state giving you a strong energetic boost.
[the file is in WAV format because the MP3 compression kills some sound frequencies]
Use this session when you really need a boost of energy.

Are you ready now to feel the energy in your ...ears?
