Query: Iggy's on a downward spiral

As a lifelong Iggy fan that owns everything he has ever recorded, it's unfortunate to report that the great one is on a downward spiral. Avenue B is a boring, agonizingly unimaginative disc that sees his creativity burnt out. Even the songs with some potential... like Nazi Girlfriend... are executed with very little flair. I have played the disc repeatedly for years with the hopes of finding something worth remembering... and it still falls flat. Even the single, Corruption, sounds like a bad Zombie Birdhouse out-take. The downward spiral continued with Beat 'Em Up... an energetic rock album with more power... but with embarrasingly bad lyrics from one of rock's greatest poet lyricists. For golden Iggy... check out Raw Power from the Stooges era, Lust For Life, The Idiot, New Values... or for more recent solid Iggy, check out American Caesar... his last great album.
