Cool Groove #2 is a Latin Rock piece.  The arrangement begins with cascading parts that build up to the melody pick-ups to the A section.  Even though this is easy material, all of the sections are equally challenged.  The melody is spread around and the basses have a moment to shine in the B section of the song.  It is also easy to add simple repetitive percussion parts, maraccas, cowbell, etc. to increase to the rhythmic interest..
