I would recommend them as follows:-

Essential:-

AMANDA MARSHALL : Amanda Marshall (probably my favourite female solo artist album in my whole collection)
Europe - Last Look at Eden (my second favourite of their comeback albums; "Bag OF Bones being my favourite)
FM : Metropolis (amazing AOR album that nearly rivals their awesome first two releases)
RICK SPRINGFIELD : The Best of (full of all his classic hits)

Highly recommended:-

Place Vendome - Streets of Fire (if you like the debut, then you will like this as well)
TOMMY FUNDERBURK : Anything For You (King Of Hearts would be a better choice)
JEFF PARIS : Lucky This Time
FM : Takin' It To The Streets


Good but not exceptional IMHO:-

Von Groove - Chameleon
Von Groove - Test of Faith
AOR - Dreaming of LA
Jimmy Barnes : Double Happiness
ASIA : Phoenix
IT BITES : Calling all the heroes - The best of
Bobby Kimball : Rise Up
