No samples without signing up – Brain.fm - Focus Music Review

So tired of giving access to Facebook or perpetually being flooded with spam just to sample a service. Before downloading this app I tried to find a sample of what to expect from this service. Nothing, nada, zip. It's music right? Why must I commit to giving my info just to get a taste of this "brain" music?
