Randomness... But nichijou is more just randomness and azumanga has a story... a bit.
If you loved Durarara!!, then you'll love Baccano. Same Author and same art style. Both are Slice of life. If you like the gangster theme surrounding the story, then you'll love Baccano.
Music-themed anime and manga, but much more realistic. If you like Slice of Life themes and Music anime, then you'll like this. :3
