I would never get into the music industry per se, but listening to music really helps me to concentrate. It's just a nice way for me to vibe and chill. There's music for when you're sad or happy or in love; there's music for every moment in life.
It is a mistake to hire huge numbers of people to get a complicated job done. Numbers will never compensate for talent in getting the right answer (two people who don't know something are no better than one), will tend to slow down progress, and will make the task incredibly expensive.
