The Voice season 12 episode 23 recap and performances
NBC/YouTube

Monday marked the Top 10 round on NBC's "The Voice" with Season 12's remaining singers competing for just seven guaranteed spots in next week's semifinals. As if there wasn't enough going on, coach Blake Shelton took to the stage to perform his latest single and wow the crowd. So who's likely to advance and who should be preparing their Instant Save performances for Tuesday night? Here's what music fans need to know from the "Live Top 10 Performances" episode:

1) Blake Shelton is still number one

It feels like Blake Shelton is always performing on "The Voice." He's a regular musical guest on the show, including three performances over the last two seasons. But watching him as he brought his new single "Every Time I Hear That Song" to Universal Studios Hollywood it was easy to understand why he's always getting asked to get up and sing. Shelton not only has a personality that can fill a room but his performances do the same. If you watch the music video for "Every Time I Hear That Song" and compare it to what he did Monday, you can see how he takes things to a whole other level live. If you missed Shelton on "The Voice" you can watch his performance now by using the media player included with this article.

2) There's still room for a good classic

The prevailing wisdom on "The Voice" is to stick with songs that are popular or at least very well-known, because that means the viewing audience will already know and like them, and in turn they should be more likely to buy them on iTunes (the ultimate standard of the show's success). But in every season there are artists who are able to wow with music that's from the classic catalog, and Monday featured some of those performances. Team Adam's Lilli Passero, who's found her lane as the one who quietly delivers consistently good covers, reached for the brass ring with a version of "Unforgettable" that audiences shouldn't forget, Team Blake's TSoul nailed "At This Moment" and Gwen Stefani's artist Hunter Plake gave us his version of "Higher Love" that went high indeed. It's nice to see the variety continuing in Season 12.

3) Will a shift in song choice save Mark Isaiah?

Everyone's eyes were on Mark Isaiah this week. Adam Levine's team member has been the recipient of two Twitter Instant Saves and just upset Alicia Keys' impressive artist Stephanie Rice, so he went into Monday's show with his back to the wall yet again. Isaiah did an interesting thing for the Top 10 round by choosing to cover a current hit in "Sign of the Times." With the aforementioned logic, will picking a song that's already in the public consciousness gain him the extra awareness (and iTunes votes) he needs to stave off elimination again? Whatever happens, he's due some credit for recognizing that he needed to do something differently and executing a course change. Hopefully audiences will follow.

"The Voice" airs Mondays and Tuesdays at 8 p.m. on NBC.
