After paring her team down to two semi-finalists last week, all Christina Aguilera had to do tonight on 'The Voice' was lead her singers through individual performances that would determine which one of them moved onto next week's finals. No pressure.

Aguilera began her mentoring by advising Frenchie Davis to cover Madonna's 1989 classic 'Like a Prayer,' but stated that they were going to take the song "somewhere it's never been," as in, apparently, to church, by adding a gospel feel. Oh yeah, why didn't the Material Girl think of that? She could have had a choir behind her while she was singing in a church for the video -- oh, wait, that's exactly what Madonna did!

Regardless, everyone really seemed to like how Davis' powerful vocals meshed with the song, with Aguilera gushing, "That took some lungs and breath, and power and control. You got it, all of it!"

After putting on her best sleeping t-shirt and joining fellow judge Adam Levine's band Maroon 5 to perform their new single, 'Moves Like Jagger' (which imitates a Prince riff and calls out Mick Jagger's swag), it was time for Xtina to turn her attention to helping Beverly McClellan sing the blues.

Aguilera stated in rehearsals that it was important for McClellan to "showcase a softer side" of her personality during her rendition of B.B. King's 'The Thrill Is Gone,' and it seems that they at least partially achieved their goal. She still relies an awful lot on needlessly dramatic phrasing, but McClellan also managed some subtler moments, particularly while seated behind the piano for the song's opening.

Of course, what one person calls overblown vocal gymnastics are what certain pop stars call "the style that bought my house, which is much bigger than yours -- and you're still renting, right?" So naturally, Aguilera loved Beverly's performance: "You are one of the reasons that I am so thankful that I signed on to do this show." (We can think of, oh, about 224,999 thousand other weekly reasons, by the way.)

But in the end, it doesn't matter what anybody but you, the voting audience, thinks about any of the performances on 'The Voice' tonight. Be sure to visit us again tomorrow night, as we keep you up-to-date about which four singers go home, and which four move on to next week's finals.
