In other cases a recording released as a single may not appear on an album.

As digital downloading and audio streaming have become more prevalent, it is often possible for every track on an album to also be available separately.

With these factors applied to the 10-inch format, songwriters and performers increasingly tailored their output to fit the new medium.The most common form of the vinyl single is the 45 or 7-inch.The names are derived from its play speed, 45 rpm, and the standard diameter, 7 inches (18 cm).The inherent technical limitations of the gramophone disc defined the standard format for commercial recordings in the early 20th century.The relatively crude disc-cutting techniques of the time and the thickness of the needles used on record players limited the number of grooves per inch that could be inscribed on the disc surface, and a high rotation speed was necessary to achieve acceptable recording and playback fidelity.Nevertheless, the concept of a single for an album has been retained as an identification of a more heavily promoted or more popular song (or group of songs) within an album collection.
