I quite enjoyed it. HCJ is going to be an excellent addition to the show. He already has been. JLo is fluff and was last time, but still she has talent and experience to add. As does Keith Urban who, country music aside, I really like. He's genuine and has a great attitude and is funny. When HCJ referred to said "licks" as utilizing "pentatonics", I was a little floored myself. ACTUAL music talk? Theory talk? On AI? Excellent. More of this will be awesome.
Another note. HCJ has been on as a guest mentor on several other seasons and has always had great commentary and advice to add. It's a no brainer that they went with him this season.
