I couldn't imagine being without music. There is music on in my house most of the time. Music centers me. I can have a really bad day and play some music- and it really takes the edges off. One of the songs that does it for me is Tommy James and the Shondells "Crystal Blue Persuasion" For some reason, that song has a real calming affect on me.
One of the benefits of that is that my daughter is really into music as well. For a 14 year old, she knows more about music than most of her peers and really enjoys alot of the old stuff in addition to the normal stuff teens listen to now. She'll chose to listen to The Moody Blues or Pink Floyd in addition to some classical stuff she likes. Out of that she plays an instrument and is learning another.
Yes, music fills a need- I couldn't be without it.
