What do these feelings mean?

Recently, I realized that I knew almost NOTHING about my ancestors. So that being said, I did extensive research and discovered that most of my family was Jewish. I don't practice Judaism (I'm a Christian) but I found it surprising that the majority of my family, on both sides, had Jewish ancestry! About a month after this discovery, when I was at a friend's orchestra performance, the conductor announced that they were about to play the Israeli national anthem. Reminded of my newly discovered heritage, I listened to "Hatikvah" for what I thought was the first time. But, as the melody began, I froze..... Completely stunned. Why? I'd heard it before when I was 5 years old, sitting in my car seat while stuck in traffic. haha I was throwing a fit because grandmom wouldn't flip my Barney tape over, when I heard the radio next to me. As I listened, I became extremely quiet and my eyes teared up.....oh, the emotion I felt! I never forgot the tune I'd heard. And to this day, it still occasionally pops into my head, evoking the same emotion as when I was 5. (I'm 18 now) My question is... why? Why would I feel such a connection, especially at such a young age? Was/is God telling me something?
