Reggaeton or "Spanish reggae," as it's sometimes called, is a genre of music totally unlike reggae in every single way despite its name. Despite some subtle differences and differing tempos, every Reggaeton song virtually has the same beat. It also always has some talentless loser rapping in Spanish about how much he loves sex. You can usually hear it playing from people's cars or ipods. The people who listen to it ALWAYS turn it up obnoxiously loud because they're insecure and want to try to impress everyone by showing them their "good" taste in music.
