Anthony Horowitz (short stories only), Stephen King (mostly for his short stories), Ismail Kadare, Jonathan Stroud, Murail.... Oh, loads more, but I've been going through a rough patch and haven't exactly chosen extremely challenging authors recently >
Too many to count.
Bach, Carl Orff, Akon, Green Day, Timberlake, KT Tunstall, Kate Nash, Simple Plan, Queen, Kanye West, Suzanne Vega, The Clash, The Feeling, Kaiser Chiefs, and the list goes on... XD
'Golem' by the Murail siblings. It's.... okay, I guess.
