I think 2000s singers and bands are so differents from the 70s, 80s, and 90s musicians. They have great style (J-Lo is a Goodess) but they're iconic for the Millenials generation. Don't kill me for what I say here, I'm not a fan of Britney or Backstreet Boys, but they have a really cool image. I see them more as style icon than music legends. They made it in a time when tecnology/PCs replaces instruments, and the voice can be not remarkable. Critics called this era of pre fabricated pop-stars. But don't get my wrong. I liked a lot the later careers of Christina, Justin Timberlake and P!nk. Britney and J-Lo are fun to heard in a good way. It's music for dancefloor, but still, far from disco divas or synth pop artists. I'm too Gen X, even I have 30 now, but I like that time the most. It was different before the digital era, same effect in media.
