I like the more obscure Abba songs
Completely off topic, but...Agreed!
Eagle, That's Me, I've Been Waiting For You, Hole In Your Soul, The Visitors, Soldiers, Me & I, Kisses of Fire, Elaine, Under Attack, If It Wasn't For The Nights, When All Is Said And Done, Dance While The Music Still Goes On etc etc...some of my favourites.
