The 2 beginner songbooks offer easier songs than the genre songbook (rock, acoustic etc…) if you are in grade 1 and 2. The genre songbooks are better suited for end of grade 2-3 and upwards. For instance, you can check examples for the rock songbook in my post here Math07 Rock songbook
Many songs in the books have video tutorial from Justin on the website (https://www.justinguitar.com/songs) so you use that to learn the songs. The tabs in the book make it easier to remember all the small details that he says in the lesson.
