I think Bryan Adams is under rated, and i am probably guilty of not listening enough too. Number 5 partly because it's greatest hits compilation as well as having new tracks on it.
#4 Janet - Janet Jackson
Another under rated musician, i think everyone gets caught up with Michael Jackson and forgets he has a talented sister. A few good tracks on this one, If and That's the Way Love Goes are my favorites.
#3 Zooropa - U2
U2 seem to be rather timeless (aside from their latest flop). Some good tunes on this one, the best are Numb and Stay (Faraway, So Close).
#2 Keep The Faith - Bon Jovi
Title track Keep the Faith the highlight on this one for mine, and if i remember rightly i couldn't stop playing it for quite some time. Bed Of Roses is also a good tune.
