Hello DocJohn its nice to meet you. I really like this website

http://www.sound-add-adhd-treatment.com/

This website uses scientific sound therapy techniques to actually address the brainwave imbalances associated with attention deficit hyperactive disorder. There are a lot of music genres to suit everyone needs. Above all there are a lot of free samples of ADHD study music.
