A single is a release of music that is shorter than an album, LP or EP. Usually, a single will get the most Radio airplay, and will be a band's most recognized work. Singles are usually filmed with music videos. They are also probably the highest quality and most compact of all music. Singles are in a bit of a cycle becoming far more popular with the advent of digital music downloads again as people no longer have to buy a full length album to hear the one or two songs they wanted to hear. Singles tend to be the dramatic beginning or the climactic ending of an album.
