List of signature songs

This is generally differentiated from a one-hit wonder in that the artist usually has had success with other songs as well.

A signature song may be a song that spearheads an artist's initial mainstream breakthrough, a song that revitalizes an artist's career, or a song that simply represents a high point in an artist's career.

Often, a signature song will feature significant characteristics of an artist and may encapsulate the artist's particular sound and style.

Signature songs can be the result of spontaneous public identification, or a marketing tool developed by the music industry to promote artists, sell their recordings, and develop a fan base.
