I suppose it's possible, but the lyrics of "This Will Be The Day" seem to fit Ruby more than the others, especially in that the last line of the second verse (You want a romantic life, a fairytale that's full of charm) seems to match what Ruby says in the first episode when she is talking to Professor Ozpin about how she is training to become a Huntress.
