Unbreakable 9/10 - One of the better songs on the album.
Heartbreaker - 5/10 - I don't like it much and I don't think it is a very MJ-like track.
Invincible - 4/10 - This sounds like a poor man's Unbreakable. It is unnecessary.
Break of Dawn - 8/10 - It's a good song, but a bit generic for MJ.
Heaven Can Wait - 8/10 - Same as the previous one.
You Rock My World - 10/10 - This was actually a good choice for a lead single (despite of MJ wanting Unbreakable, I think). It is one of the best songs on the album. As time went by it grew on me even more and now I think it is a good addition to MJ's catalog that could rightfully make it to an MJ best-of album.
Butterflies - 6/10 - I am not as much a fan of this song as many other fans seem to be.
Speechless - 6/10 - Same. Over the years some of MJ's most saccharine songs grew on me but this never managed to.
2000 Watts - 4/10 - So out of character for MJ IMO.
You Are My Life - 7/10 - Yeah, simple, nursery-rhyme and all, but it's something that MJ could get away with for me due to the sincerity with that he could sing such songs.
Privacy - 3/10 - If I have to name the worst song in MJ's entire catalog this would be a strong candidate.
Don't Walk Away - 7/10 - It's OK, but again, it is way too generic for MJ IMO.
Cry - 5/10 - I am no big fan of the ballads R. Kelly wrote for MJ.
The Lost Children - 6/10 - Very average from MJ.
Whatever Happens - 10/10 - Besides You Rock My world this is the best song of of the album. It should have been single, it should have had a video, instead of Cry.
Threatened - 10/10 - This is a song that I seem to like more than the average fan. I read MJ wanted a video for it and I would have loved it. I like the idea for how the rap was made of Rod Serling's speech and I love the lyrics. Interestingly, it might be I most listen to from this album apart from YRMW.
Overall, as I have said in previous discussions of this album, my big problem with Invincible is that to me it is the least MJ-esque album of all his albums. Often I feel that much of it hardly has anything to do with him and those tracks that are his songs are not among his strongest songs. When I read Mike Smallcombe's "Making Michael" book that only confirmed it to me that this was the album MJ was least interested in and least involved in.
