Kendrick Lamar has released his new album To Pimp a Butterfly a week before its scheduled release date. There's a bit of confusion as to whether this was supposed to happen, or whether someone messed up.

Lamar seemed pretty okay with things, tweeting, "Keep calm. All is well," though Anthony Tiffith, Top Dawg's chief executive, said, "I WOULD LIKE 2 PERSONALLY THANK @Interscope [Records] FOR [...]ING UP OUR RELEASE... SOMEBODY GOTS 2 PAY 4 THIS MISTAKE !!!! #TOP."

Other than the first three singles I, The Black the Berry and King Kunta, all the songs on To Pimp a Butterfly were unannounced. As it turns out, the album features the likes of Flying Lotus contemporary Thundercat, George Clinton and Snoop Dogg. The Isley Brothers frontman Ronald Isley also makes an appearance. 

One person who's most certainly enjoying the new record was none other than Taylor Swift, who tweeted, "KENDRICK PUT HIS ALBUM OUT EARLY. NO ONE TOUCH ME."
