In the field of recorded music, side A and side B , also known as side A and side B (from English A-side and B-side ), are the terms with which both sides of the discs are known. 7-inch vinyl on which the musical singles were originally released in the 1950s . The terms derived in the denomination of the types of songsconventionally located on each side of the disc, side A being the main song, the one that the producer of the disc intends to get rotation in radio stations and eventually become a hit, and side B the secondary song that It does not usually appear on the album and it serves as unpublished material to promote the sale of the single .

The earliest 10-inch, 78- rpm shellac records were engraved on only one side. Double recording, with one song on each side, was first introduced to Europe by Columbia Records and by the late 1910s had become common both on that continent and in the United States . Sides A and B already existed, although neither side was considered more important, and in most cases, radio stations would play any of the songs on the album. The side did not connote anything about the contents of the disc.
In 1948, Columbia Records introduced 10-inch and 12-inch long- playing vinyl , and rival RCA-Victor responded the following year with the 7-inch, 45-rpm record, which would replace the 78 as the standard for singles. At first, most record labels would randomly assign which song would be on which side. Under this random system, many artists would achieve the so-called " double sided hits " - double sided hits - since both songs on the album would climb the popularity charts or appear on jukeboxes.In public places. Over the years, the convention for assigning songs to the sides changed. In the early 1950s, the song on side A was the song the record company wanted to promote, while lower quality recordings, instrumentals, etc. were included on the B side.
With the advent of cassettes [ 1 ] and compact discs in the early 1980s the differentiation between the two sides became much less prominent. At first, the cassette singles often had a song on each side just like vinyl records, but later the maxi single cassettes, which contained more than two songs, became more popular. With the decline of cassettes and the rise of compact discs, the side A / side B dichotomy became virtually extinct, as this new format lacked the physical characteristics for two-sided recording. However, the term "B-side" is still used to refer to the bonus tracks on a CD single.
Finally, with the advent of digital download methods over the Internet , sales of CD singles and other physical formats fell, so songs that are not part of an artist's album repertoire are generally put up for sale. in the same download catalogs, referred to as "previously unavailable", "bonus", "rarity" or "exclusive".
Double side A
Technically, a single with "double A side" is one that is released without a B side defined as such, that is, the two songs - both the front and the back of the record - function as side A. Therefore Both are equally important. This made sense when the record market was based on the vinyl record industry , when record companies promoted their releases on radio formulas. If a single came to a station classified as "double side A", it meant that there was no dominance of one side with respect to the other, but that both had the same conditions to be broadcast. On the other hand, if one of them had been classified as "B", it would not have had the same diffusion as its respective face "A".
Examples of "double sided A" famous are " Strawberry Fields Forever " and " Penny Lane " by The Beatles , [ 2 ] the re - launch in 1991 of " Bohemian Rhapsody " with "These Are the Days of Our Lives" of Queen , [ 3 ] both on side A with "Bijou" as side B or, likewise, the double side A of Nirvana with " All Apologies " and " Rape Me " on side A and "Moist Vagina" as side B of both.

Double side B
A "double B side" single is one that has one song on side A and two songs on side B, for a total of three songs. Before, these types of formats were considered " maxi single ", but technically they were not, since a maxi single in use had to contain at least four songs to be able to form a mini-album.
Famous examples of "double sides B 'are, to name some of them," Many Too Many "of Genesis on side A and" The Day the Light Went Out "and" Vancouver "on side B. [ 5 ] the single from Paul McCartney 1980 "Coming Up" had a studio version of the song on side a, while the B side contained two songs, a live version of "Coming Up" and an instrumental study called "Lunchbox / Odd Sox ».
