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
I found another interest site for at least listening to music. It is Bob's Ballroom Broadcast. He introduces the music with what he considers as the music should be. You do search online or if you have the tunein app it is found there.
