U2 caused a stir when their new album Songs of Innocence was instantly made available on iPhones and iTunes libraries everywhere. When Tyler, the Creator discovered the album on his phone, he got pretty mad about it and let Twitter know exactly how he felt. His central message? "FUCK BONO."

He wrote:

The day Songs of Innocence was released, Bono wrote in a note, "For the people out there who have no interest in checking us out, look at it this way… the blood, sweat and tears of some Irish guys are in your junk mail."
