Nothing tops the original, but these come pretty close.
  1. Adele, "I Can't Make You Love Me" (originally sung by Bonnie Raitt)
    The song is already perfect but when you add Adele's vocals to it, it sends it into a galaxy all its own. http://youtu.be/sLfWPLLn-QI
  2. Kacey Musgraves, "Mama's Broken Heart" (originally sung by Miranda Lambert)
    I don't know if this falls under the category of a cover since she's one of the co-writer's, but it is AMAZING. http://youtu.be/ulnI__oY3Yw
  3. Adele, "Make You Feel My Love" (originally sung by Bob Dylan)
    Ugh, this makes me fall in love every time I hear it. http://youtu.be/LLoyNxjhTzc
  4. Stevie Nicks, "I Need to Know" (originally sung by Tom Petty and the Heartbreakers)
    Stevie's been doing this cover off and on in her live shows since the 80s and it's still amazing. (This clip actually has Tom Petty and the Heartbreakers in it, which just makes it even cooler.) http://youtu.be/QxIK4zCPITo
  5. Adele and Darius Rucker, "Need You Now" (originally sung by Lady Antebellum)
    I'm a Carolina girl so I'll always have a soft spot in my heart for Hootie. As for Adele, I would listen to her sing my AP History notes from high school. http://youtu.be/gwxYjcYBd5A
  6. Martina McBride & Kelly Clarkson, "Does He Love You" (originally sung by Reba McEntire and Linda Davis)
    Two powerhouse vocalists shooting dirty looks at each other while singing about the man they share? Yes, please! http://youtu.be/2lzr6MaWicQ
  7. Little Big Town, "Born This Way" (originally sung by Lady GaGa)
    Who would have thought that putting a bluegrass twist on a Lady GaGa song could sound so fabulous? Not me. (Honestly, though, all of their videos from their Scattered, Smothered, and Covered series are great.) http://youtu.be/xa_l_GZyXCU
  8. Martina McBride, "We've Got Tonight" (originally sung by Bob Seger and the Silver Bullet Band)
    The longing she infuses into this song kills me. http://youtu.be/f3tmjCKAUoU
  9. Stevie Nicks, "Crash Into Me" (originally sung by The Dave Matthews Band)
    Show of hands of people who thought they'd ever see Stevie Nicks and The Dave Matthews Band in the same sentence. But honestly, she takes this song and infuses it with her own brand of mystical, dreamy magic. http://youtu.be/7CM8l0Qp210
  10. The Band Perry, "Gentle On My Mind" (originally sung by Glen Campbell)
    It's a cover that would make the Wichita Lineman proud. http://youtu.be/rNsdWycw-MM
  11. Darius Rucker, "Wagon Wheel" (originally sung by Old Crowe Medicine Show)
    This song is home for me, even more so when it's being sung by Darius. http://youtu.be/IBkIR1mIkaU
