Man, I think Get Lucky is SO much better than On Sight. I'd like to hear the others too but Get Lucky is pretty fucking amazing, just got overplayed was all.
That's it though. I've heard it so much that I'd listen to literally any other song on RAM than Get Lucky and be happy. On Sight with Kanye, Contact, or Doin' It Right are all movers and would work fantastic, minus the language on On Sight, but worse has been done at the Grammys so it's possible.
