I don't think I've listened to any other album released in 2014 (I'm mostly stuck at older stuff), but Aphex Twin's "Syro" is a great one. Surprised nobody here has mentioned it.
Personally, I respect Aphex Twin but I've never been able to get into his music. However, David Rees released a mashup of Taylor Swift and Aphex this year that I enjoyed a lot. I also enjoy Girl Talk's use of Aphex's music in his mixes.
I've also had a hard time getting into big part of Aphex Twin's music. I guess it often isn't the most catchy one ("Selected Ambient Works Volume II" is the best example - one of my favourite releases of his, also one that I had the hardest time to get to like). But his art as a whole (covers of his records, videos, ideas, his overall creepiness and vastness of genres/moods his music spans) had always kept my interest in the music big enough to get through the hard shell. And the more I listen to his releases (and he released tons of music under at least 6 different aliases), the more I dig and appreciate it.
