I love musical synchronicity (no, not referring to to the Police album, although I love that, too). I love it when the music comes on and is a perfect soundtrack to whatever you're doing at the moment. Like the time that I ran out of Wal-Mart during an unexpected downpour. I started my car and Natasha Beddingfield sang to me "...feel the rain on your skin!.." Last night we got a good one. We went to a midnight showing of Tucker and Dale vs. Evil. After the movie got into the car and my favorite station was playing hillbilly music. (Followed up by some alternative rock, so it's not like it is a mono-genre station.)
What's your favorite example of musical synchronicity?
