there has been some research linking music to depression though at this point they are not clear wether music causes depression or people with depression are more likely to binge on music. i feel that both the assertions are true - excessive consumption of music can lead to depression ( through the same mechanism as porn ) and if a person is depressed they are more likely to binge on music ( for the dopamine hits ) and it can become a bad cycle. having said that, i think playing a musical instrument is not as bad as listening to an endless playlist of every kind of music available on earth. i think playing an instrument can be compared to sex while the music in your ipad or smartphone is much like masturbating to porn. but its best to avoid both while rebooting.
