As a long time fan of Abba, I purchased the original import releases of all of their albums years ago, along with Greatest Hits volulme 2 for Gimme Gimme Gimme and Summer Night City. Then, I had to supplement. I bought More Abba Gold to get "I Am The City". I bought the "Thank You for the Music" boxed set to get a whole load of previously unreleased tracks. I RE-bought the domestic release of Voulez Vous to get the original version of "Lovelight." I bought the Definitive Collection to get the 12" of Voulez Vous. Now-I've gotten rid of ALL of that, because it's ALL on here, and the remastering sounds better than ever, even on their very first albums.
As for the packaging-the CDs are made to look like vinyl LPs, and they are black coated, so the bottoms of the discs look like Playstation 1 games if you've ever seen one of those. The box itself is a soft velvety sky blue with a pull off top. Inside, there are slots for the 9 CDs, 2 DVDs, a hardcover book of liner notes for all the CDs, and a hardcover booklet with lyrics for every single song on every disc. There are actually MORE slots than components, so the box is bigger than it needs to be, but you can at least space your discs apart to get them out easier. Each of the 8 ABBA albums comes in mini cardboard record sleeves, with the art work from the original LP on front and back. Inside, each disc is in a clear plastic slip case, and there's a single sheet insert with the track info for that disc. Unfortunately, since this box is set up so that each of the 8 albums includes all the bonus tracks recorded at the period of that album's release, the original artwork on the disc sleeves does not list the bonus tracks, so you either have to remove the insert or use the hardcover book to reference them.
The ninth CD is all the bonus material, unreleased tracks, long versions and extended versions. And here's where you find the only two big disappointments. A previously unreleased alternate mix of Waterloo is included-but as the liner notes state, it's mastered from vinyl because the original master couldn't be found-and it sounds like it. But the BIGGEST disappointment is that for the first time ever, the long version of "On and On and On" is included-but a stereo master was unavailable, so a MONO source was used. And considering this is such a clean, bass heavy dance track, the mono is painfully shrill and dull. Bummer. This version features an added bridge of lyrics and an extended fade at the end. Maybe someday a stereo master will be found, and we'll have to do supplementing once again with a future "Ultimate Abba Collection with one previously unreleased track!"
And don't forget-unless you have an all region DVD player, you won't be able to play the 2 overseas DVDs.
Bottom line: hardcore fans should not HESITATE to get ALL their Abba all in one place.
