Meh

Interface:
Needs to be redone. Its too loud and distracting.

Packaging:
Are you kidding me? 20 different versions of this app with repeating sounds from version to version? And people though Vista versions were complicated.
Release 1 full paid one and a couple free demo ones. New sounds could be purchased in-app if needed after a 2-3 play preview.

Music Tracks:
Good, would be nice if this app included all the ones that the author released for free as well.

Brainwave Effects:
No complaints here. Maybe a better organization interface.
