Agreed on 'Solid Gold' and, to a certain extent 'Blah Blah Blah'. I rather enjoyed Iggy's couple of albums after 'Blah...' too. A bit 'big-hair-metal at times, but 'American Caeser' has some cracking tunes on it.
I'd even argue a case for Tin Machine II...Baby Universal and I Can't Read being two of my fave renaissance-period Bowie.
