The album was amazing overall, but this is also fantastic in its own way. I don't see how this is a "copy" of Oh Superman, unless you want to imply that any sound can only be made in one song. The chord progression is totally different and the "similar" sound is only made for a fraction of the song's length.
I personally think this sounds more like The Knife's "This Is Now", but in a good way, not a "what a blatant rip-off!" kind of way.
