Nice try aye. Seriously, made me think a bit.
As a listener, I can feel strong indirect connection to song lyrics or, otherwise, interpret it in some metaphoric way I feel connected to.
It's a sin deals with the issue of younger generations being pressurised by their older superiors into certain way of thinking and behaviour, and the ability to question that and go your own way despite that pressure and direction. You don't need to have grown up Catholic to feel connected to that.
The Theatre raises social issues. They affect everyone, not just the homeless. The dictator decides takes it to the global level. Everyone who is not indifferent to the global situation and the presence of authoritarian regimes in the world can feel connected to it.
A quintessential example would be Can you forgive her? (which made me a PSB fan and has been my most favourite PSB track since then) — despite what the lyrics are literally about. I was 13 back then, barely understood English and could comprehend none of the lyrics except for the title. But nonetheless I strongly perceived the song as being about facing facts and admitting truth that is difficult to accept. This is universally applicable, not just to boyfriends accused by their girlfriends of being gay.
Unlike all the above, I don't see how to generalise or take in a metaphoric way a song explicitly talking about a man still feeling attraction to his former male lover he accidentally comes across in public. Unlike all the above, this is intimately personal. You either see yourself in the scenario, or it is not for you at all.
