In the Zone is Britney Spears' fourth CD. I think that it definitely has a different sound, compared to her other previous CDs. But I'm not sure that I like it as much as them. It is still a pretty good pop CD, but I think that a lot of the songs sound very electronic, which I don't really care for.
"Me Against the Music" is one of the best known tracks on the CD, and Madonna even makes a special appearance in it. It's a good, upbeat song. I also like the song "Toxic", which has kind of a weird, different sound to it, but it's still pretty catchy. Other than those two songs, I really don't think the rest of the CD is that great. I guess those types of songs aren't really my style. Some are kind of a hip hop sound, and others are slow, sappy ballads.
Overall, this CD has a few good songs, but I would recommend getting any of Britney's other CDs before this one!
