Saying that you 'get' a song just like the artist intended - or in other words that if you tried you could do that too. Or, that you're just like they are, that, so here's some writing that shows I think just like musician 'X'.
That just shows that you're insane.
This video by Talking Heads shows that I 'get' this song.
I'm just like Bavid Bryne.
He thinks that identity is the most important factor in the things that you do and vide-versa - and so do I (and so do I do not).
Or perhaps David Bryne is just really good at expressing ideas with poetry.
