Using Google when I was searching for some Legend of Legaia tracks I found this site, some various posts with Winamp playlist contained the phrases I looked for.

What I'm looking for exactly are unofficial tracks of this game. The official soundtrack The Legaia I already have, but there is a collection of unofficial tracks out there like the Boss Battle Theme that last 2 or 3 minutes and Koru Battle Themes 1 and 2.
I once owned these tracks but I somehow managed to delete them.

If anyone has any of these tracks and would go through the trouble of pointing out a download link or uploading it I'd really appreciate it. ^^

This, in turn, also means that if anyone wants tracks of the OST I'd also be glad to upload the entire collection.
