The six hundred and seventh album: #607 Michael Jackson - Bad
It feels like there just isn't much to say here already. Michael Jackson is such a known name, and the songs well known enough, that I don't think I need to describe Bad or Smooth Criminal. It's his brand of pop, including funk and some rock, produced to perfection, which some evocative lyrics and a great beat serving a good track. It's varied - there are some quite touching ballads, and it all feels more real than you might expect it to be. Of course this is absolutely worth it.
