There isn't much that is more attractive than a gorgeous girl playing and singing a song like an angel. That is a scientific fact. However, like the sirens in Greek mythology, a girl like this can also be very dangerous, luring men in with her enchanting music and voice, and making us do dumb things. But that's a risk we're willing to take with our weekly feature of hot girls playing and singing hit songs for your enjoyment. This week's ukulele cover of "Nothing Else Matters" by Metallica comes from a user on YouTube who goes by the name Puffin312. Try not to fall in love.
