After Adam Levine and Usher's teams competed Monday night in the first Live Playoffs episode of "The Voice" Season 4, on Tuesday it was time for Blake Shelton and Shakira's contestants to give it a go. The episode started off oddly, when Blake took his all-country team to a karaoke club to rehearse, which wasn't exactly the best way to change public belief that all singing shows are basically glorified karaoke. But hey, who wouldn't want to hang out with Blake Shelton at a karaoke bar? That sure sounds like an awesome night out to me.
