As other posters have said, song choice is very important to me. If I can't relate to a song at all it is difficult for me to pay attention, let alone evaluate or critique. I have five favorites at this time. Four of them made song choices that resonated with me and the other sang something that is not a personal favorite but is familiar.
In the order they appeared (maybe not exact but close) they are: Janice Freeman (Radioactive), Brooke Simpson (Stone Cold), Esera Tualo (Rise Up), Meagan McNeal (Can't Feel My Face) and Jon Mero (Versace). "Stone Cold" and "Face" (the relationship interpretation not the addiction one) are relevant to me personally. Although I am more familiar with other Andra Day songs, such as "Red Flags" and "Gold", I was surprised and pleased with Esera's choice.
Maybe I hallucinated this, but during one of the blinds segments, I thought I heard Miley say, more than once, that she wanted to win with "country". IIRC that ideation evidently disappeared.
