Oh yeah Chiddy Bang, ive been listening to them for a while too they are pretty good. The only thing they have against them is that they just sample existing songs and make something completely new out of em. I like "All things Go" "Never" and " "opposite of adults".
Zion - I is really good too. saw the duo three times in the last two years and they blew me away. I really like their remix of Rebelutions 'Safe and Sound'
im not that big into rap and hip hop anymore so i cant really say whos good nowdays. ill check out some of the guys you listed , thanks. Lately ive shifted into more of indie, dubstep, reggae and embarrassingly some poppy and some blue grasstype type of music. Edward Sharpe and The Magnetic Zeros, Passon pit, Bassnector, Rusko, Soldiers of Jah Army, groundation, slightly stupid vampire weekend to name a few.
I have come across one group in the pacific northwest called the Blue Scholars, you probably havnt heard of them but I find them very refined and sometimes has a jazzy feel to them.
