I can't stop listening to the record - and actually I don't really think Reflektor (the song) is as "catchy" as it first appeared. Definitely Here Comes the Night is the most accessible, anthem-y track. But I think We Exist, Normal Person, and Joan of Arc are pretty catchy too. That whole run from We Exist to Joan of Arc (5 tracks) is bad-***.
I'm getting more into the second "disc" now as well, the three tracks from Awful Sound to Porno are big, riffy songs. I like.
