Music or no music... That is the question?

My whole life has been choreographed. From warm up to cool down and everything in between. Dance goes hand in hand with music. Up until running this was the only exercise I had known except for walking. Music had always been a huge part of my life and for a long time, my job. Many will say they can't fathom running without music, but more long distance runners will actually be angry with people for using music on race day. So the big question and debate is A-should runners be aloud to use music and B- Is music enhancing or hindering when it comes to marathon running and beyond.
When I first started running I was just like everyone else, me and my trusty iPhone were stuck together like glue. I had a long running playlist but, due to my dance training, I had the whole run choreographed. I had a warm up song, pace songs (not at first, just your basic keep moving fat girl songs), then speed it up songs and finish strong songs. I was constantly updating my playlist, looking for better songs and had varied type of run playlists. For example; I had a men suck running playlist, I'm stressed playlist, I'm happy playlist and running sucks playlist. I was ball and chained to the music instead of enjoying the run.
About 3 weeks before my second marathon and 2 days after my 20 mile run, I was hit by a car. Don't cry for me Argintina! It was barely a tap on the leg and my right calf muscle was sore for a few weeks. I realized I was paying more attention to the music then my surroundings. The next day I gave up the music. It was the best thing for my running. I was no longer playing with my head phones, distracted by the music. I listened to my breathing and heart rate. My runs seemed shorter and I actually felt more in the moment with my thoughts. I also learned I say way too much out loud and swear like a sailor! My second marathon actually seemed shorter without the music. It took me longer than my first due to my knee giving out but it was actually more enjoyable.
I personally will probably not run with music ever again but I understand that some people need it. I don't think its fair to tell people they can't use it but, many races ban the use of head phones. It is very distracting. I can understand the reasoning behind it but whatever can get you through 26.2 miles, use it. Running without music has really improved my game and with only a month to NYC I'm ready. Plus there are 130 bands playing so I will be free to enjoy the party... Kinda!
