I recently got a copy of Legend of Mana, and after playing it a bit, decided that out of all the Seiken Densetsu games, this is the only one that actually has decent music all the way through It's got a decent mix of rock tracks and gentler tracks, and the OST seems much easier to listen outside the game than for the other Seiken Densetsus, e.g. Seiken Densetsu 2 (Secret of Mana) has a really bland soundtrack, and Seiken Densetsu 3 which has a few good tracks, but they're overwhelmed by more average tracks.
Anyway, out of the games from this series, which of their soundtracks do you prefer the most?
