rare2005,
Totally agree with your observation.
Regarding Debo, many times he missed on pronunciation, and mood of the song. Also, looks like he had song lyric in front of him. I am not sure why/how everyone agreed to let him sing (or not sing) from song-lyric. He failed miserably and ID realized that within few seconds. As soon as mentors finished putting numbers, and keep in mind that those points were not that low after seeing Debo poor performance, ID walked out.
I am a big fan of ID (and his music) but was very disappointed to see him behaving like a child. In past, we all have seen ID praising and supporting the singer who performed well. But, this time he let us all (his fans) down by his behavior.
