It's very easy: You hear the first few (mostly) instrumental seconds of an ABBA song. All you have to do is pick the correct song title. That's all.
|You like the music and have a Greatest Hits album||You have most of their albums and some singles||You're a long time ABBA freak (probably since Waterloo)|
|Hits only||All the album and single tracks||All songs, including demo-only songs, but without the hits|
Please note: if you have a slow connection (56K-modem) then loading a sound-file might take a couple of seconds.
