Singing that makes me want to stand up and cheer

I saw this clip of this woman rehearsing to sing in the movie and as you can see in the clip below, she got really into singing it and had such passion in her voice that it really made me want to stand up and cheer for her somehow. I just like seeing people get all enthusiastic about doing something they clearly love to do and that they find passion in the doing of it. Although the woman in this clip is clearly emotional, I felt like I could hear a lot of joy in her singing and it did my heart good to hear it. If there's something that you want to do and you're passionate about it, I hope you can always find the joy in doing it.
