Bowie: The Platinum Collection is (rather obviously) a collection of David Bowie's greatest songs spanning almost 20 years of his fantastic and inspiring career: 1969-1987 (his better years) across 3 CDs, which is an overall impressive CV.
Disc one contains the majority of his better known hits such as the sublime "Space Oddity", "Rebel Rebel" and "Changes" as well as album tracks from 1969-74 (which, in terms of just 6 years, 20 excellent tracks is extremely impressive).
Disc two contains his greatest songs from 1974-79, which includes the cocaine-influenced "Station To Station" and the "Berlin trilogy" (Low, "Heroes" and Lodger). This disc has a particularly unique and more conceptual feel to it compared to the other 2, but it is perhaps the weakest of the three in my opinion, but still essential to the David Bowie collection-plus it contains the sheer breath-taking "Heroes" (It also includes the excellent "1984", an album track from the brilliant "Diamond Dogs" album).
Disc three is probably my personal favourite disc, it spans 1980-87, ultimately Bowie's weakest years for albums (aside from 1980's "Scary Monsters") but perhaps his strongest era for hit singles, such as "Let's Dance", "Modern Love" and "Ashes to Ashes". This CD also manages to put the minority of great album tracks and singles from perhaps the worst albums "Never Let Me Down" and "Tonight". The final track being "Labyrinth (OST)"'s "Underground" is a great finishing touch to a superb- and essential- collection of the greatest male solo artist's finest work.
