As far as I know, nearly all societies have developed music, as part of their cultural development. 10000 years ago, there were instruments to make what we would recognise, as music. I am not sure how good their HiFi systems were, but they had music. From memory, researchers have looked at changes in EEG's when people are listening to music.
Another very interesting recent discovery, is that speech and musical ability are quite separate. A stroke sufferer, I believe, lost speech, but could communicate by signing sentences. Weird, but true.
