Actually, I feel that way about all of The xx's music.
What's the point at being that good at building up something, but NEVER EVER paying it off? There's an obscene metaphor I could make here, but I'm going to keep this post classy. Besides, I already made you think about it anyway, so sorry. There are more propulsive re-mixes of this song that do have more of a payoff. I guess I just need dynamics in my music. Dynamics are what make waiting worth it. Song's pretty good, though, I guess, if you really, really enjoy foreplay.
