"Bohemian Rhapsody" is a song written by Freddie Mercury and originally recorded by the band Queen for their 1975 album A Night at the Opera. The song is in the style of a rock opera, and has a very unusual musical structure for a piece of popular music. Its six different sections have no chorus but both a cappella and heavy metal arrangements. Despite this, it was released as a single and became a huge commercial success. In addition, the song is widely hailed as Queen's magnum opus, and it marked a decisive point in the band's career and setting them on the way to become one of the world's most popular music groups.

Another One Bites the Dust" is a 1980 funk/rock song from the English rock band Queen, written by bassist John Deacon and was a worldwide crossover hit (hitting number one on the U.S. Billboard Hot 100, hitting #2 on the R&B charts, and the Disco Top 100). It was successful on the R&B charts because some fans thought Queen was a R&B group. In the band's native UK, the song peaked at #7. The song is Queen's best selling single and their biggest hit to date, with sales of over 7 million copies.

"Fat Bottomed Girls" is a hit single by the English rock band Queen. It was released in 1978 on the album Jazz. The song was written by Queen guitarist Brian May and was one of the few Queen songs played in an alternative guitar tuning commonly called "Dropped D Tuning". The lyrics express the axiom "Beauty lies in the eye of the beholder", although the song has a humorous and overly sexual tone for such a serious subject.
