Somebody That I Used to Know

Somebody That I Used to Know by Gotye feat. Kimbra was featured on my Fall play list yesterday, and I must confess:

I'M OBSESSED.

I first heard this song on the August play list that Miss Moss put together. This song is so great, and I'm not sure what it is specifically, but I do know my co-workers are probably getting sick of hearing it blare out of my speakers all day. What do you guys think - GREAT SONG? PERFECT FOR FALL? Let me know...
