Only heard a few tracks off 'Seek Magic' by Memory Tapes but it sounded great too. Lots of other good ones already mentioned (the cribs, Jay-z, ian brown, doves etc)
Already excited about next year too, looking forward to stuff from Delphic, The Good Natured, Alex Metric, Beach House, The Depreciation Guild and lots of others, 2010 should be a cracking year for music.
