A megamix is a medley remix containing multiple songs in rapid succession. There may be only one verse or even just a brief chorus of each song used, sometimes in addition to samples of the same or other songs. There may also be some elements of bastard pop in some, though not as much as a mashup^{[citation needed]}. To unify the songs together smoothly, a single backing beat may be added as background throughout the megamix -although this is not a must-. This backing beat is kept basic so as to simplify mixing and to not compete with the music. These mixes are usually several minutes long at minimum, going up to a half-hour or even more sometimes.

Ultimix is known for "flashback medleys" producing at least one or two every year based on popular songs of the year. Each is about 15 minutes long, usually with at least that many songs if not more.

"Album megamixes" feature all tracks from a particular album edited and compiled into one continuous medley. The "artist megamix" is also popular, including songs spanning a musician's career, with prolific artists such as Michael Jackson having more than one, usually from different remixers. Duran Duran created a megamix single from their own hits for the 1990 greatest-hits album Decade: Greatest Hits. Subsequently artists such as Madonna, Britney Spears, and Janet Jackson have also released megamixes as singles in order to promote their greatest hits albums or in the latter's case studio album. Many megamixes are bootlegs.

Stefani Joanne Angelina Germanotta (/ˈstɛfəniː dʒʌrməˈnɑːtə/ STE-fə-nee jurr-mə-NAH-tə; born March 28, 1986), known by her stage name Lady Gaga, is an American singer and songwriter. Born and raised in New York City, she primarily studied at the Convent of the Sacred Heart and briefly attended New York University's Tisch School of the Arts before withdrawing to focus on her musical career. She began performing in the rock music scene of Manhattan's Lower East Side, and was signed with Streamline Records by the end of 2007. During her employment as a songwriter for the record company, her vocal abilities captured the attention of recording artist Akon, who signed her to his label Kon Live Distribution.

Lady Gaga came to prominence as a recording artist following the release of her debut album The Fame (2008), which was a critical and commercial success that topped charts around the world and included the international number-one singles "Just Dance" and "Poker Face". After embarking on the The Fame Ball Tour, she followed the album with The Fame Monster (2009), which spawned the worldwide hit singles "Bad Romance", "Telephone" and "Alejandro". The album's success allowed her to embark on the eighteen-month long Monster Ball Tour, which later became one of the highest-grossing concert tours of all time. Her most recent album Born This Way (2011) topped the charts of most major markets and generated more international chart-topping singles, including "Born This Way", "Judas" and "The Edge of Glory". Besides her musical career, she involves herself with humanitarian causes and LGBT activism.
