The song “Always Been You” explores the emotions you feel when you can’t stop thinking of that one person, but you realise that they aren’t feeling the same and you are bound to get hurt by reality. “Cause in my head it’s always been you” this line is the staple of the song and is the lyric that gets the main point across about how this person is always in your head and they are all you can think about no matter how hard you try no to.
