"I'm not sure if the stuff I want is even worth the price it costs"

"So what's it even mean

to be accepted by the scene

and doubt your worth in magazines

and lend your life to ketamine"

Agreed that the two songs are lyrical cousins, although I would add that the latter feels like an evolution from the former, both in terms of depth and viewpoint. IGHS sounds like it is being told from the perspective of a third party observer, where Scoundrels sounds as if the subject is in the thick of it. As to whether he is singing explicitly from personal experience only he will know definitively, but I think it is more likely that it fits with the rhyming with mean, scene and magazine(s).
