Facebook posts, do they mean anything?

Ok so this girl I really like just put this on facebook "your voice is the sound track of my summer" with a heart, now I know I'm going to sound beyond stupid on this one, but does this mean anything, I pretty sure this wasn't addressed to me considering we really only text and I haven't seen her much this summer, so do you think this means she likes someone, or is she just quoting that cheesy song hahaha? Let me know what you think! Thanks!
