Two Songs: Marc Anthony, Preciosa. I am a huge Marc Anthony fan and I love all his songs but the first time I heard this song, I cried. I heard it in Puerto Rico while driving over a beautiful mountain and it was so moving. It's a cover and he did an amazing job. It really exercises his vocal chords as well.
Buena Vista Social Club, Chan Chan. A truly beautiful song.
Here's a better version that I wasn't allowed to embed.
