[ Discussion ] What's the first μ's song to make you shed a tear?

Seriously!! What's the first μ's song to make you emotional? The first one for me was Snow Halation actually. I played the game without watching the anime and knowing nothing about Love Live in general, but for some reason, Snow Halation got me. It pulled me in!

So guys, I ask again, what's the first μ's song to make you emotional? :)
