My favorite was "Song in my head; keep it." I feel like it's talking about more than just music.
My only critisizm would be that these are all about separate things- peer pressure, grades, parents, etc.
I think you'd be looking within yourself deeper by coming up with one that encompasses all areas of yourself, and perhaps is not so obvious what it is about.
I love that you were able to come up with so many though! Our assignment (in my english) was to make three, and it took me a good fifteen minutes just for that!
My favorite is "Your life is determined by you". I really really like that one. It really struck home.
