I don't care for the EZplay books but I bought these books from Mike to get his custom GENOS USB which comes with the bundles.
He does a song a week (posted on Youtube) from one of the songbooks in the bundles. He creates a custom style for the song with a special OTS setup. He also creates a registration for each song with the custom style, tempo etc. He also copies the pages of each song with his notes and mods (legal I guess since you have to buy the books).
The USB includes the styles, regs and the copies of the song pages with his additions. He emails updates when he does a new song.
I've posted an index of the songs in his two 5 book bundles in the EZplay songbook forum which might be useful to others.
