Indeed; according to the articles, they've also got a song called "Unfamiliar Ceilings", and one of their albums, "Grand Unification", is apparently supposed to be a concept album about Eva. And while with any other band I'd think it was a major stretch, given the number of Eva references they've stuck into their titles, I wouldn't doubt if their album "Be Human" got its name from "At Least, Be Human", and I can easily guess what the song title "H.I.P. (Enough)" stands for.
With that said, though, the (admittedly little) research I put into them after discovering their existence a few months back led me to conclude that other than the titles there isn't really a whole lot of Eva-ness to the actual songs. "Unfamiliar Ceilings" is about sleeping around and having lots of sex, if I remember right.
They also have songs called "Lost Like Tears In Rain" and "Where's The Money, Lebowski?", so I think it's more just a case of them writing a song and then picking a name for it from a show or movie they think is cool.
