ROL. IMHO, the key is not the problem. It fits his voice just fine. Since Adam is a Diva, and since he was working with Ricky Minor, I am sure he picked the key. The biggest problem was that Adam couldn't FUCKING HEAR in order to be on pitch at the beginning. He knew it. It was live, he couldn't do anything about it. The show must go on. But, he looked supremely uncomfortable. Once they fixed whatever the sound problem was, he got on track and got into it.
The other problem, again IMHO, is the song itself. It's got a great dance beat. Can imagine peeps head pumping in the clubs. But, musically, it's just not interesting. There isn't much to it in terms of melody, arc, variety, or musical development throughout the song. It sounds repetitive. And, what are the lyrics about? I don't get a sense of emotion, of story, of a point to them. Adam is a great lyrical and musical interpreter, but I don't think there is much to work with in ROL. YMMV
