"Emo seems mainly to signify various things to different people," says the author. But, above all, music is determined by the stage of life in which people listen to it. Thus, an "emo stage" could refer to any one of several different phenomena: the emotional intensity of this music; the age of the listener; or both. The first use of the term "emo" was in 1993, when the Cleveland-area rock band 7eventh Time Freeze released a self-titled album that was popular among high school students who listened to alternative rock at the time. The album included songs with intense emotional responses such as loneliness, depression, and anger. After the success of this album, other bands emerged using the "emo" label, including the more mainstream No Doubt (who were originally called "New Radicals") and the less popular Jawbreaker. In addition, many young people started listening to alternative rock again, this time under the name "emo." During this period, many articles about "emo" appeared in magazines such as Rolling Stone and Spin. Some critics believe that these articles contributed to making the alternative rock scene even more focused on emotions than before. Others point out that "emo" was used because this type of music was very popular with teenagers at the time.
