Your trial is probably long expired by now, but I'll throw in my picks anyway.
Antony and the Johnsons - The Lake EP: Recommended. Anything by these guys is just gorgeous. (3 tracks, one of them being Fistful of Love, which can also be found on 2005's I Am a Bird Now)
Camera Obscura - I Love My Jean EP (3 tracks, not their best work, but ok)
Beirut - Pompeii (2 tracks, the first - Fountains and Tramways - is one of my favorite Beirut songs)
And I'll second bdb's suggestion of Swing Your Heartache by Young Galaxy, but only if you don't plan to get the full-length s/t. The third song, Golden Coin, is just fantastic, but the others are on their full-length, which I highly recommend. Just about the best album of '07. I think my love for Young Galaxy should be well documented by now...
