I missed out on the poll, though my input would've been far from stellar; I'm woefully behind when it comes to new VGM releases. Gyakuten Saiban 5 Original Soundtrack gets my top pick for 2013; it doesn't quite reach the absurd highs of Gyakuten Kenji 2, but it's just as good as Iwadare's other works in the Ace Attorney series.
A close second, a lot of folks likely missed out on Taylor Davis's Melodies of Hyrule: Music from The Legend of Zelda arranged album, which I'd made a previous thread about here. A shame, as I think it's one of the more dynamically impressive Zelda arranged albums in recent memory. She currently has music videos out for the tracks Song of Storms and Gerudo Valley. I also uploaded Tal Tal Heights & Zelda Main Theme, a stunningly rousing highlight of the album.
