All Day is the fifth album by American mash up musician Girl Talk, released by the record label Illegal Art on November 15, 2010 as a free download. The album consists of 373 overlapping samples of other artists' songs.
All Day was released as one seamless 71-minute MP3 file and as 12 separate tracks. The Illegal Art website stated that the album was "intended to be listened to as a whole," but was "broken up into individual tracks only for easier navigation."

Girl Talk, Wiz Khalifa, Big K.R.I.T., and Smoke DZA have announced a collaborative new album. Full Court Press is out April 8 (via Asylum/Taylor Gang). It’s the first full-length Girl Talk album Gregg Gillis has released since 2010’s All Day.
According to a press release, the four of musicians started working on the album in 2017. “These guys all go back with each other over 10 years, so it was just a great energy in the room,” Gillis said in a statement. “I wanted to have an environment where they could do what they do best; try out a bunch of different ideas and have fun with it.”
