Query: Many Good Songs Worth Buying

I think Abba is so underrated, because their harmonies are so absolutely beautiful. This CD has several songs on it that are worth buying to keep..."The Visitors" is a song that is just fun to hear. But others, like "One of Us" and "Like an Angel Passing thru my Room" are those stop still songs that make you pause and remember. A song that can be sad "Slipping through My Fingers" is so gorgeous and so relatable to anyone seeing their child growing up, and it was just featured in the "Mamma Mia" film. Note the beauty of the front cover of the CD...the rich golden color and the way the members are standing apart, with the ceilings high around them. It is worth a buy because it's not all about one good song. Let's get back to worthwhile, classy music.
