What genres of music were popular in the late 1990s?

In the late 90s, there were a few dominant genres of popular music: boy bands and the so-called "Latin Explosion." Boy bands usually consisted of 5 members, each with a distinct "look" that's desirable to a range of (usually) teenage girl fans. Their songs were usually "bubblegum pop" or love songs, all with catchy hooks or choruses. Popular groups in the late 90s were the Backstreet Boys, *NSync, 98 Degrees, and O-Town. "Latin Explosion" artists were Hispanic/Latino or of Hispanic/Latino descent and the songs sometimes featured Spanish words or phrases, along with Latino beats in otherwise standard pop music arrangements. Some popular acts include Ricky Martin, Jennifer Lopez, Marc Anthony, and Enrique Igelsias.
