I don't really care about copyright or not. I love the soundtracks from Beowulf. If you're not going to include them in your next release, then that's your choice. Btw, PoP also has some tracks from KoH and whatnot, so I don't really see the deal on this.
I'll add the Beowulf musics in again for my own use in your next versions. I like this pack so far, thanks for sharing.
