From Finner by Of Monsters and Men
"My head is an animal" was a surprise for me and probably the album I've listened to the most in the first part of 2012 (before my Smiths phase, but that's quite a different story: just be glad it's inappropriate for me to rant about it here). If a song is about the sea (or seagulls, salt and sushi - but this last one is pretty rare), chances are that I probably like it: and this happens to be my favourite track off the album, indeed.
The Enemy by The Raveonettes
A more personal choice: my memory will always link this song to a beautiful concert I attended last December in Paris. I like how even the Raveonettes' songs that sound lighthearted and bright, always come with a slightly dark accent, a hopeless sort of reminder that, well, we're doomed anyway.
