This song is really really really ridiculously good.

The Ōsaka Loop Line 大阪環状線 is a railway line in Japan that encircles central Osaka. It's also my new favorite song by Discovery, a super-fun-experimental-bubble-gum-electro-pop band made of the good stuff kids love: Rostam Batmanglij, the keyboardist from Vampire Weekend and Wes Miles, Ra Ra Riot's main vocals.  
Just to give you an idea, their influences include: "subwoofer, pitchshifted handclap, that sixteenth note high hat you're hearing in da night, highlighter yellow/neon orange."  That means that while it's bubbly and makes you feel amazingly happy, you can still turn up the bass and make the trunk rattle!!!  
This is the kind of song you listen to when you first wake up in the morning, when you know it's gonna be a lovely day...which is every day, duh! Listen:
