If I had to pick 4 at this moment based on overall feedback of the artists + pimping thus far...
-Thunderstorm Artis (artists like Thunderstorm rarely go far but his audition received the most buzz by far, and for good reason.)
-Todd Tilghman (Team Blake always has someone in the finale, let alone the top 2. All he has to do in order to be in the runner-up position is to make the playoffs, unless Blake busses him for...)
-Toneisha Harris (She's 2/2 for being leaked and so far both of her performances were very well received. She also has a very emotional story that singing show fans love. Blake was very serious with his pitch for her, I get the impression that he really wants to get her far.)
-Allegra Miles (this one's up in the air but they're obviously going to want Nick in the finale or a winner, and Allegra is his best shot at this current moment.)
