I've seperated the game origins from the tracklist, because the note field is a better place to store such informations. It's better to keep it as original, as possible.
Two tracks had wrong translations. I've replaced "Village" with "Mission of Mana", because the japanase tracklist says "Mana no Shimei". I used "A Conclusion", the original module track title (taken from my SPC collection), for track 5.
I've also added the artists to the database, to make our "doujin artist network" more complete. I heard these names already, so we'll need them someday. Their translations should be correct, so it shoud be okay to have them already stored.
The mana label page went offline a few month ago, so it was necessary to finish this.
