Mine is hands down 2010. The year of so many will-be classic albums: Arcade Fire - The Suburbs, Wild Nothing - Gemini, Tame Impala - Innerspeaker, The National - High Violet, Four Tet - There is Love in You, Caribou - Swim, Flying Lotus - Cosmogramma, Joanna Newsom - Have One on Me, Beach House - Teen Dream, Deerhunter - Halcyon Digest, LCD Soundsystem - This is Happening, Kanye West - My Beautiful Dark Twisted Fantasy, and may I dare say, Manic Street Preachers - Postcards from a Young Man (just to name all the ones I've listened to). Not only the best year so far of the 2010s, but probably the 2000s as well.
