If we can count digital stuff we didn't pay for (promos), I'm at 75 for 2013. Otherwise, I'm at 61 for 1988.
Edit: iTunes tells me 1185 albums, but my iPod tells me 1202 albums (they have the same number of songs though). I also have about 15 more CDs to rip to my computer, and a few of them are from the 80's, so it's hard to say. '88 should still win out though.
