Finally, after 200+ episode celebrating iconic pop releases, we're going track by track through an Ace Of Base album. And what an album! Now do keep up, as this episode is all about Happy Nation - but not the original version of the album, this is the U.S. version, which is very similar to their debut American album, The Sign. Got it? You will. As always do let us know your thoughts on the album and the episode @trackbytrackuk
