I saved the best for first: "Byrds of Prey" by Bertie Blackman. Fabulously fantastic. I haven't been so obsessed with a song since I first heard La Roux. Must be listened to with good headphones at least once.
"Audacity of Huge" by Simian Mobile Disco featuring Chris Keating. It wasn't love at first listen. In fact, at first I thought it was Eurotrash techno. But after a couple times, I started really hearing the words and was struck with the sheer coolness of this song.
Passion Pit- "Little Secrets." I'm speechless. MTV2 describes it as "Indie Disco," and I don't think I could do any better than that. I might venture to compare them to an amped-up MGMT.
"Allein Allein"- Polarkreis 18. Yes, it's a German band, and the title translates to "Alone Alone." The message is rather depressing if you stop to think about it, but I don't because I can't get over how hauntingly lovely this song is.
Hot Chip- "Take It In." I strongly recommend listening to this one on the ol' headphones too. A much more pensive, piercing Hot Chip than you may have already heard in "Ready for the Floor" or "Over and Over."
