The term 'confessional rock genre' is often associated with the three-letter acronym EMO. This genre of music emerged in the mid-1990s and is characterized by its emotionally vulnerable lyrics, often dealing with topics such as heartbreak, depression, and anxiety. It is often seen as a subgenre of punk rock, indie rock, and alternative rock. The genre has become increasingly popular over the years, with many bands and artists gaining recognition for their work.
