I don't know how many of you have hear of i-doser, but basicly its a long ass song that puts wierd tones in your brain. litterally. lol
Basicly what it does is change your brain waves and makes you feel like whatever drug your listening to. Its for educational purposes, and doesn't actually hurt you in any way.
The bad part about it is that you have to listen to the whole song to get the whole affect.
Lengths of song go anywhere from 6 minutes to 45 minutes
