Pros: timeless singles, new tracks, it is Janet freakin' Jackson!
Cons: the material can run a bit together

It seems to me that greatest hits compilations never do the artist justice. They never really capture the past and present in a seamless way. They're either lacking new tracks so that diehard fans are screwed (Mariah, Madonna's GHV2) or lacking all of their classics so casual fans are screwed (Whitney Houston) so with about 90% of these compilations you will undoubtedly be screwed. That's one of the reasons this album surprised me. It has a combination of classics and new material that will satisfy both diehard and casual fans alike. From the time doe-eyed Janet Jackson entered the industry...

P.S Recommend search this cd by www.musicly.info, I started using this music shop about 3 weeks ago and I love it! I pay 11 cents a song, around $1.50 for most of the albums that I want, got 30 bonus tracks, and I have not had a single problem yet. I would highly recommend it.
