Melanie Martinez The Voice

Big news for NBC's "The Voice" -- executive producer Mark Burnett announced that both Usher and Shakira will be taking seats in the spinning chairs in Season 4, replacing Christina Aguilera and Cee Lo Green, as the latter record, tour and generally be awesome.

Never fear, however -- this change-up is only for Season 4; Burnett had said previously that with seasons filming in near-rapid succession, he wanted to give his coaches some time to, you know, actually have music careers.

Besides, Blake Shelton and Adam Levine will still be coming back, so we still have that delicious bromance to celebrate.

Ah, but we're still on Season 3, aren't we? Blind auditions continued Monday night, as the four judges slowly fill out the 16 slots on their teams.

Melanie Martinez, 17, of Baldwin, NY, with Britney Spears' "Toxic"

This adorable little gap-toothed girl (who rocks Cruella De Vil-style hair) turned judges' chairs with her quirky, acoustic take on "Toxic." Though both Adam and Blake vied for her selection, she went with Adam.

Summary thoughts: She played a tambourine with her feet. She's OK in my book.

Brian Scartocci, 26, of Austin, with Stevie Wonder's "Isn't She Lovely"

Brian's soulful take on Wonder's classic -- dedicated to his two children -- again had both Adam and Blake spinning their chairs. Blake, for the second time this season, pulled what has become known as "The Vest Card." "I, too, wear jeans with vest. You have soul, and I have a soul. I think we have some serious chemistry," Blake said. But Brian went with Adam.

Summary thoughts: Anyone that asks Blake, "Would you wear pink with your vest," and elicits the response "I've got on some pink right now, you just can't see it," wins all the awesome points forever and ever more.

Beat Frequency, from Washington, with Katy Perry's "E.T."

This husband-and-wife duo (followed by a quick montage of other duos that failed to make the cut; clever editing, NBC! I see what you did there!) were just a little weird, which I guess was apt given their song choice. But Christina liked them -- she was the only judge to spin her chair -- so they found a spot on her team.

Summary thoughts: Any time a person tells me they tried to "pursue a career in sports dancing" I lose interest and start judging. Besides, the husband was wearing sunglasses indoors, and I'm sorry, the only person cool enough to do that on "The Voice" is Cee Lo (because Jack Nicholson is regrettably absent).

Liz Davis, 25, from Nashville, with Gretchen Wilson's "Here for the Party"

Liz got three chairs to spin, but appropriately and predictably, out of Adam, Christina and Blake, she went with Blake. It was nice to see him finally take a contestant from Adam, because, really, this was just getting sad.

Summary thoughts: I claim no expertise when it comes to country music, but to me, Liz was just not that good. Her performance just seemed clunky. She could hold her runs, but she was running out of breath at the end of sentences. Conserve your breath! Prioritize! (I have learned this from singing in the car, inadvertently entertaining others in rush-hour traffic.)

JR Aquino,  from Alaska, singing Bruno Mars' "Just the Way You Are"

This Alaskan YouTube sensation got the attention of Adam, Cee Lo and Christina, with Cee Lo noting that JR seemed to have trouble hitting the high notes. Because of that constructive criticism, JR went with Cee Lo.

Summary thoughts: JR was good, and I can see him progressing at least a few more rounds in the competition, but I'm so over this song.
