It's a fascinating idea, but I'm not aware of any research that shows effects of binaural beats on mood or subjective mental state in a controlled experimental trial. The wikipedia page cites some sources showing effects of audio or visual frequencies on the frequencies of neural oscillation; but given that not much is known about how neural oscillations relate to subjective mental states, that doesn't tell us much (I mean - it's interesting, for sure; but it doesn't tell us much about getting high from certain frequencies). Most of the claims of subjective effects on the wiki page are uncited, or cited only to non-peer-reviewed books. One citation (http://www.liebertonline.com/doi/abs/10.1089/acm.2006.6196) which does show an effect (i.e. different subjective mental state before and after exposure to binaural beats) lacked a control condition, so that's pretty weak evidence at best. I'd be very interested if you could give a reference for a published study that reliably demonstrates subjective effects of binaural beats.
Oh surely, but that could be for all sorts of reasons other than the frequencies of binaural beats impacting on subjective mood via entraining of neural frequencies (the proposed mechanism for 'auditory drugs', iiuc). For example, loud or fast music is likely to be more arousing simply because we are evolved to respond to intense stimuli with increased alertness; also, we may have cognitive and emotional associations with different pieces of music because of when and how we experienced those pieces of music (or similar sounding pieces of music; since associations do generalize) in the past.but when you listen to certain music, doesnt it make u relaxed and/or happy?
