The worst disappointing albums for me were:
Megadeth: Risk - what the hell, this is a great pop album, If you like pop, but where the hell is heavy metal? Dave and co went sell-outs with this one. This album should not have MEGADETH name on it.
Warmen: Beyond abilities: Shit, all those synthesizer solos make me want to puke! I really thought that this band was worth of effort, but no!
Unleashed: Victory: All the songs are mid-tempo and sound like same shit all over again.
-All the metallica albums after ...and justice for all.. : James Hetfield and Lars ulrich cannot make good songs anymore..
