Say what you want about Miley Cyrus, the girl can sing. Her voice is absolutely crazy. Miley recently went on BBC Radio 1 in London. They have a great bit giong where any artist who comes in to perform in their Live Lounge has to perform a cover of their choice as part of their set.
Miley picked Lana Del Rey's massive hit, Summertime Sadness, and completely crushed it. I think this version is actually even better than the original.
