There is not a single point in history, not a single diversion, not one alternate time line, where Maiden "should" have deliberately made themselves more accessible, dumbed down, or radio friendly.
This has to be a troll post - it has to be. Rod Smallwood mismanaged the band by not pushing them to be more mainstream? Come on! You really wanted Maiden to release a "Black" album, or a Turbo Lover? You want Bruce up there duetting with Lady Gaga? You want homage paid to Maiden by Avril Lavigne or Snoop fucking Dogg? To have albums artificially tightened and over produced to hell by Bob Rock or Andy bloody Sneap? All in the name of selling a few records to some idiots in America who'll buy anything with a mindless hook or easy lyrical content?
I think you're listening to the wrong band, mate. Go back to your Linkin Park or other easy to digest, mindless earworm pap.
