So far 'Dont Shut Me Down' has it for me. Gets moving in traditional Abba style and has a Cliffhanger ending.
'Still Have Faith' although great writing, is clearly internally meaningful to them and goes on a bit too long.
However I wonder if these are the 'best' tracks on the album, hence the push.

PS - I'm a firm Abba fan BTW who still thinks Visitors album their best album.
