Question about a crush

So, I have this crush I like.
She has been flirting with me occasionally, being rude and mean (in a joking way), and she rests her upper arm on my shoulder whenever we watch a movie in class. [I'm 16]. She also calls me a cute nickname heaps.

She knows I like to make music remixes, and often sends me things that she wants me to remix.

One of the songs she recently wanted me to remix was off a show called Degrassi - One of her favourite shows. I'm going to copy and paste part of the lyrics below:
"Can you come closer
And show me that you're mine
So tell me if it's real baby
Tell me if it's not
This is how I feel baby
I hope it never stops
I hope it never stops
I hope it never stops
Boy we got this chemistry
I swear it's not the drinks
We gotta make this last longer".

She claimed that she didn't even think about the lyrics, and that it's just one of the songs she likes.

Do you think she likes me? How could I go about finding out for sure? Thanks!
