In reality this isn't new - it seems Lykke Li's "Get Some" is 12 years old. I just heard it a few weeks ago.
It's an ok song. Honestly, I was more taken by it when I heard on the radio (ooh ooh ooh on the radio), but it's got a decent vibe.
Maybe it's me, but it has a quasi-Bananarama-esque thing going on. Maybe part of their earlier years? I can't quite pin it down. It also has an "Iko Iko" thing going on too.
I won't be buying it or adding it to a running playlist anytime soon, but it's different yet oddly familiar.
