Zach Sobiech is singing with the angels now.

Zach died Monday at the age of 18 after a battle with cancer, but he left behind more than just memories for those who knew him.

After learning that he only had a few months to live, Zach decided to write music as a way to say goodbye. A lot of music. Eventually, he released an album on iTunes that featured the song ‘Clouds,’ which became a YouTube sensation and garnered a lot of interest among people who knew his story and even those who didn't.

This video shows how extraordinary a person Zach was and makes you truly appreciate all you have. You can honor his legacy by donating to the cancer research fund he launched.

Rest in peace, Zach. Wach the video for Zach's song 'Clouds' below.
