nah, you are not alone. i do not get it neither... I can see how people like it as the harmonies are still similar to the older stuff but all in all it is a bit too playful and cheery/hectic for me.
I do not like the jazzy post rock moments. I do not mean to sound rude but the stuff on "oh" reminds me of minotaur shock, capitol k, leafcutter john, etc. Not bad but not my cup of tea. Wish there'd be another So record sometime.
I think I'm the only one that doesn't like the new Oval.. the abstraction was what I liked about the old stuff so much..
