My opinion...
I don't believe this music directly makes anybody more intelligent.
People who LOVE listening to it, however, kind of "space out" to it, which IMO is just thier brain processing large amounts of information.
Processing large amounts of information makes one smarter.
Its kind of the same thing as saying Meditation will make people smarter. No, it won't, but it will HELP PEOPLE MAKE THEMSELVES SMARTER.

but of course..... that's just MY opinion... I could be wrong
