The order: 1-5 my top 5 albums. 6-10 the next 5. 11-20 just other interesting stuff.
Stripped Back Sad Albums: Bright Eyes, The Antlers, The Tallest Man On Earth, Regina Spektor, Arcade Fire (not so much stripped back but still sad)

Rock with hard-core elements (kinda emo if you will): Brand New, PUP
Electronic and Synth based: LCD Soundsystem, Radiohead, Animal Collective, of Montreal
