If you’re trying to figure out the direction of the clave (2-3 or not 2-3?) in any song, listen to the harmonic rhythm. One chord for 2 measures or more (a slow harmonic rhythm) will usually work best in 3-2 clave. “Footprints” is a good example. When there are more chords, or a faster harmonic rhythm, you’ll find mostly 2-3. May the clave be with you.
