1) Passion Pit - Manners
Easily my favorite album of all time. Every song some how manages to blow my mind in some sort of fashion. It's famous for it's hits, but really it's all around the best blend of music ever.
2) Daft Punk - Discovery
This one doesn't need an introduction. Seriously, I've been listening to it since it came out when I was in 4th grade, and it still never gets old. Completely defines how I feel about electronic music, with the various uses of samples and just incredibly catchy melodies/lyrics.
3) The Mars Volta - De-loused in the Comatorium
Nothing to really describe this album. Just listen to it on some sort of drug and you'll get whats happening here.
