ABBA was all about the harmonies and those can definitely be found here, along with plenty of disco cheesiness. "Dancing Queen" is not something I didn't hear on a regular basis in my childhood, but I don't want to hear it for pleasure, personally. "Fernando" is a beautiful song, but again, what do a bunch of folks from Sweden know about crossing the Rio Grande to freedom? But anyway, "Take a Chance On Me" and "Mamma Mia!" also make appearances, along with a number of other songs including hits like "SOS" and "Knowing Me, Knowing You." If you want ABBA, then yuo have come to the right place.
In the background for each song plays a music video, which struck me as odd since a lot of these songs came out well before MTV. The quality of the video is really poor, but again, you have to consider the timeframe. I would have thought they would have cleaned them up a little, but they didn't for the PS3 version, so I guess its no surprise that the PS2 wouldn't have any cleanup either. If you are in the mood for some nostalgia from the golden age of disco, you'll surely find it here.
