What are flip side songs?

Flip side songs are songs that are released as the B-side of a single. In the early days of vinyl records, the A-side was considered to be the main track, while the B-side was used to fill up the remaining space on the record. However, over time, B-sides began to be seen as an opportunity to showcase an artist's experimental or lesser-known work, and some B-sides have become even more popular than the A-sides they were released with.

Here are some examples of famous flip side songs:

* "Respect" by Otis Redding (B-side to "(Sittin' On) The Dock of the Bay")

* "Strawberry Fields Forever" by The Beatles (B-side to "Penny Lane")

* "Hey Jude" by The Beatles (B-side to "Revolution")

* "All You Need Is Love" by The Beatles (B-side to "Baby, You're a Rich Man")

* "Gimme Shelter" by The Rolling Stones (B-side to "Honky Tonk Women")

Today, flip side songs are often released as digital downloads or as bonus tracks on albums. They can provide a valuable opportunity for fans to hear a different side of an artist's music.
