When did you know that music was your passion?

Was there a specific moment in your life when you realized that music was your passion? Was there a defining, earth shattering moment while listening to a certain piece of music that stopped you dead in your tracks? For me it was when I was 12 years old. I snuck downstairs into my syster's room while she was out. I used to watch her play records so I new how to turn on the "forbiden" stereo. I took a record from its sleave, put it on the 'table, and dropped the needle. Jimmy Page's opening riff of "Whole Lotta Love" shot through me like a bullet, and I was paralized. At that moment, music sunk its hooks into me and hasn't let go since. What about you?.......
