I have to say, this is one of Britney Spears' best songs. But, the single was just lacking. There were only 4 tracks, it was less than 15 minutes long. The "Instrumental Version" of the song was pretty cool, I wish they would include those on more singles, but there wasn't much more on this single. "Walk On By" is a nice little non-album track, not the best I've heard, but it was pretty good. It's more of a slower song. The one remix included was pretty short. It's a cool little slower remix, not that dancy, but good nonetheless. I was expecting more remixes on this single, which would have been nice. This single is recommended for Britney fans, but not many others beyond that. All in all, this is just an o.k. single, and worth passing up. Enjoy!
