While you're at it, could you also collect or flag the songs with harder-to-identify beats? Often, a beat is a distinct percussion or emphasis. However, some songs seem to have a hidden or implied beat, making them harder to count than usual.
This would be useful for preparing competition when you don't know what songs are going to be played.
I have taught dancing for years. So many students just learn to dance a certain dance to a certain song. Start listening to the beat of the song. The song will always tell you what dance to do to it. My theory: People hear a song but we don't listen to a song. We are so use to having music all around us that we quit listening to it. The Look of Love- Rhumba Dream. Dream, Dream- Rhumba or a Cha Cha
