I picked two relatively easy lines because it would be easier for you guys to learn and also use in everyday life!!!!!

Might be a little confusing without some explanation but basically 같다 which is the base word for 같다면 means to be "the same" but adding 면 turns it into an if statement! So this sentence means "If you are the same as me" !!! You can use this structure for other words~ 

For the next one: 

이제 불러 따라 (hoo)
격하게 털어 (ayy-oh)
You know I'm fire
 그냥 맘대로 움직여 

Let's break it down~! 

Firstly!!!! The word 그냥 is very commonly used and you guys should get used to it (as you can tell with the fact that we've already seen it twice). But as you can guess, this sentence means "Just move/act the way you want to." The reason I picked this lyric was because they used 맘대로 which is a very common phrase used by Korean people and while the full form is 마음대로 (마음 meaning like heart/mind) which kind of means "whatever your heart desires." The short form - 맘대로 is how we say it outloud (gets shortened if you say it fast!!!! 

This is kind of a long one but I want to teach this phrase to you!

If you haven't guessed already, the lyric basically means: You never know if my feelings will change just like the weather. I love this lyric and also love that you guys can use this phrase in daily conversation!
