Music

For people who love M.I.A. but are dying for a new album, I would try first Sleigh Bells [like their song Crown on the Ground] and then some of Kanye West's pieces and the remixes/mashups.
In general, mashups are a great source of songs for M.I.A.-style music lovers. Kanye in particular has many songs that naturally approach a type of mashup level in complexity and artistry. His piece Dark Fantasy is one, as is Blood on the Leaves and Stronger.

A very long, almost half an hour piece mixing Kanye's music is the Mega mix which is really absorbing. It's a great mix of beats and his songs.

Like M.I.A.'s music, these songs have a natural rhythmic progression that is very involving and great to listen to. For fun, try the Kanye Christmas album, a hilarious rerecording of his latest album Yeezus. The word substitutions are really fun and it's so creative.

There's a neat Yeezus mashup of the whole album into one single piece here, which is really nice.
