Thus far I'm digging the new Tegan & Sara, Heartthrob.
It definitely continues their trajectory into more straight-forward pop territory, subverting the edges that were still present on Sainthood despite the polish. It's Tegan and Sara at their most "commercial." I kind of hate that designator, but it's convenient here (plus it's less obnoxious than "accessible"). As a result I can understand the negative reaction it's solicited from some of their fans. To hear the twins now, something like So Jealous seems a million miles away sonically at first blush. Really though, the continuity with their older work is still there.
They really sound a lot like Uh Huh Her at times though.
Not my favorite track on the album. That would be "Goodbye, Goodbye," "Drove Me Wild," and "Now I'm All Messed Up."
I really liked their "Are you ten years ago" song. :)
