This is a song I wrote the day I heard my son's heartbeat for the first time. There was this little gel covered microphone swirling around the outside of my wife's very pregnant belly! The nurse was having a time find our shy guy. But then there it was, this little rhythm. It was pretty fast, 180 beats per minute (i guess thats normal for a baby). I recorded the sound on my phone and its the exact speed of this song. you can hear the heartbeat on the beginning and end of the track. See if you catch the double meaning in the songs lyrics.
Enjoy
