/\ :Thumb: - he DEFINATELY stole the show.
stefan - Start with 'Purple Rain' - his biggest-selling and most popular album, make sure you get the movie as well.
Then buy "Sign O The Times", his prophetic and eclectically astounding double CD masterpiece from 1987.
I would then suggest you pick up "Dirty Mind" from 1981, and "Parade: Soundtrack to 'Under The Cherry Moon'" from 1986.
Then, buy the triple CD set "The Hits/The B-Sides", and continue on your own based upon which songs from there you enjoy the most.
