1. We've Had Enough (best): Easily the best of the Darkchild tracks. Like a rockier "Earth Song". Forever will be a shame that it wasn't on Invincible.
2. Escape (2002 version): Of the hip hop-ish Darkchild tracks, this is the best one. I'm not really interested in hearing MJ angrily complain about his life as we already heard him do that on History and this song is a little too mechanical, but it's still better than any of the Darkchild tracks that were on Invincible.
3. Unbreakable: The best Darkchild track that did make it on Invincible. The album really should have been named after this song, because it's exactly what I would have thought the title track would be like (if they wanted to avoid confusion with the Samuel L. Jackson movie, then they should have renamed the song "Untouchable" and called the album that). My main complaint against it, though, is the same as my complaint against "Escape". Angry, cocky MJ wasn't interesting to hear anymore. I also don't think songs with heavy digital production like this was the right direction for the album to take. Oh, and the Biggie sample was completely unnecessary; should have gotten a living rapper like Jay Z instead.
4. Threatened: It's definitely a poor man's "Thriller" and sounds like an 'N Sync or Britney Spears song, but I still like it. At least it's better than the tracks that feature Fats, lol.
5. You Rock My World: Generic Darkchild production, but I like it. Quite refreshing to hear a laidback, easygoing song like this when all of the other Darkchild cuts on the Invincible are aggressive.
6. Heartbreaker: Generic 'N Sync esque pop and wannabe Timbaland-style production. Loses points for including Fats. But I don't dislike the song.
7. Invincible: More generic 'N Sync esque pop. Easily MJ's worst title track. Will forever be stupid that someone thought it was a good idea to have "Unbreakable", "Heartbreaker" and "Invincible all play back to back at the start of the album, as well as the fact someone thought it was a good idea to have Fats on not just one, but two tracks. To this day, we're still wondering who the hell he was. Still don't dislike the song, though.
8. Get Your Weight Off Me: We haven't heard the full song yet, but I can tell from the leaks that it's in the same vein as "Heartbreaker" and "Invincible". Don't tell me Fats is on this, too. :/ Still, I'd love to hear the full thing soon.
9. Escape (2014 version): Don't care for this at all when it's just a glorified remix. It's not bad, but I'd rather just listen to the song how MJ intended it to be. This remix just turns it into a generic mid-2010s pop song. Yawn.
10. Privacy (worst): One of the worst songs on any MJ album. Just corny self-indulgent garbage with dumb lyrics and overly coarse vocals.
