Beach House was approached to license the song but they refused. So the ad agency apparently hired someone to recreate the song.
This is what Beach House has to say on the matter:
“Hate to have to address this VW ad story during our release week, but an important part of information wasn’t included in the news story. The ad agency actively tried to license “take care” from us for weeks, to which we politely declined. People’s comments/ anger should not be directed towards VW or us. It was the ad agency that made these moves. I hope this also clarifies to fans and non- fans just how “take care” and the vw ad song are related. We will release a proper statement weeks from now when we don’t have more interesting things to do/ talk about.”
You can support Beach House and order the album ‘Teen Dream’ which contains this song.
