According to Daryl's Library, this CD is in fact a combination of two albums, the Seiken Densetsu Original Soundtrack and the arranged album 'Let Thoughts Ride on Knowledge'. The website goes on to say this game (being on gameboy) is actually the first game in the Mana series but it was released as 'Final Fantasy Adventure' in the United States. The following US titles were Secret of Mana and Legend of Mana. Good thing I found that because I became horribly confused at the offical Square-Enix album database. (Nephtis)
The album's Japanese title reads something like:
"Seiken Densetsu - Final Fantasy anecdote - Sound Collections"
I imagine 'Final Fantasy Adventure' sounded better than some kind of side-story. But yes, this title was indeed the first 'Seiken Densetsu' - literally 'Holy Sword Legend'. (Nephtis)
