All Day is the fifth studio album by American musician Gregg Gillis, known by his stage name Girl Talk. The album was originally released as a free digital download by Illegal Art on November 15, 2010. Gillis composed the album using overlapping samples of 372 songs by other artists. All Day was released as one seamless 71-minute file and as twelve separate tracks, available in MP3 and FLAC. As with prior Girl Talk albums, All Day was ‘intended to be listened to as a whole,’ but was ‘broken up into individual tracks only for easier navigation.’
