The anticipation and interest in Girls' Generation's first-ever sub-unit Taetiseo has been explosive to say the least, so it's no surprise that fans will be pouring over the trio's long-awaited debut mini-album that was released today!

As yesterday's song previews revealed, the mini-album 'Twinkle' contains seven tracks, which validate Taeyeon, Tiffany and Seohyun's powerful vocal talents with a variety of song styles. From the slow-tempo "Baby Steps" to the funky "OMG" (does anyone else get the "Chocolate Love" nostalgia?), these ladies have certainly stepped things up with this mini-album.
