A mixtape is a compilation of music, typically from multiple sources, recorded onto a medium. With origins in the 1980s, the term normally describes a homemade compilation of music onto a cassette tape, CD, or digital playlist. The songs are either ordered sequentially or made into a continuous programme by beatmatching the songs and creating seamless transitions at their beginnings and endings with fades or abrupt edits. Essayist Geoffrey O'Brien described this definition of the mixtape as "perhaps the most widely practiced American art form".

The Compact Cassette, also commonly called a cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips, the Compact Cassette was released in August 1963. Compact Cassettes come in two forms, either containing content as a prerecorded cassette (Musicassette), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed—for example the Microcassette—the generic term cassette tape is normally used to refer to the Compact Cassette because of its ubiquity.
