A-side and B-side

About A-side and B-side

The A-side and B-side are the two sides of vinyl records and cassettes, and the terms have often been printed on the labels of two-sided music recordings, which in purely technical terms of recording and playback do not favor any side over the other. The A-side of a single usually features a recording that its artist, producer, or record company intends to be the initial focus of promotional efforts and radio airplay, with the aim of it becoming a hit record.
