Songs

If you`ve ever listened to song lyrics closely you know that most of them are about relationships - past, present or future. How true are the words? I know people in relationships who sing of women that I'm sure are not their GFs - are they fictional situations or people from the past, or worse, the present? My BF doesn't exactly talk about his feelings, yet his new song talks in detail of 'missing' someone...should I be concerned? Granted, it's just a song, but the thought of him a) remembering in detail a past relationship b) confronting these feelings and c) revealing them to the (technically) entire world makes me a bit uncomfortable. Just saying.
