I'm gonna be honest, I've never heard Invincible. If I'm not mistaken, the only songs I've heard from the album are Butterflies and You Rock My World. Btw, the live performance of You Rock My World where Chris Tucker and I believe Usher come out and join Mike on stage is one of my favorite performances ever. Probably because I'm a big Chris Tucker fan, but yeah.
Yeah, pretty much the only songs from his album I've heard 10 years ago (IIRC?).
