http://scienceblog.com/77379/listening-to-classical-music-modulates-genes-that-are-responsible-for-brain-functions/Why is it that such studies always look at classical music? Specifically Mozart. It's becoming a cliche, and might obfuscate some results, for example related to what type of music you like.
Is there a study on how metal music improves concentration and other things, separating the results into groups which like the type of music from those who don't? Because I think whether you like it or not probably has a lot to say.
Besides that this study here is a little weird. In its title we have "music modulates genes", suggesting they are able to connect the effects to genes, although from what I can ascertain there's only talk of functions which are
associated with certain genes. I suppose if no other study has looked at it that way it might be of some interest; "a shared evolutionary background of sound perception".
