Query: Good Pop Sound

They're a pretty good band. They are 2 guys and 2 girls and it's surprising how good their voices blend. I saw them in concert last summer, before they even started making their new album. They were so good, and Robbie was really good looking. I will see them again this summer. The best song, I think is, That's What You Get. The next single which is really good, and pop oriented was written by JC Chasez of NSYNC. If you like NSYNC and Britney, all in one sound, you should get Boyz N Girlz United's CD.
