Way to assign global hot keys to go to the next/previous album in iTunes

If I understand your question correctly, in the 'music' section, sort by date added, select the six albums worth of songs and create a New Playlist from Selection (Cmd-Shft-N, or right-click on selection). From that playlist, you should have the view you want.

You can use KeyRemap4MacBook with a private.xml such as this:

<?xml version="1.0"?>
<root>
  <item>
    <name>⌃← & ⌃→ to ⌥← & ⌥→</name>
    <identifier>remapCtrlLeftAndCtrlRightToAltLeftAndAltRight</identifier>
    <autogen>
      __KeyToKey__
      KeyCode::CURSOR_LEFT, VK_CONTROL | ModifierFlag::NONE,
      KeyCode::CURSOR_LEFT, ModifierFlag::OPTION_L
    </autogen>
    <autogen>
      __KeyToKey__
      KeyCode::CURSOR_RIGHT, VK_CONTROL | ModifierFlag::NONE,
      KeyCode::CURSOR_RIGHT, ModifierFlag::OPTION_L
    </autogen>
  </item>
</root>

I'm not aware of any System Preferences setting regarding this.

With regard to comment, change the contents of the <autogen> to…

__KeyToKey__
KeyCode::CURSOR_LEFT, VK_OPTION | ModifierFlag::NONE,
KeyCode::CURSOR_LEFT, ModifierFlag::CONTROL_L

__KeyToKey__
KeyCode::CURSOR_RIGHT, VK_OPTION | ModifierFlag::NONE,
KeyCode::CURSOR_RIGHT, ModifierFlag::CONTROL_L
