-Kobas- I really loved the second one that you sent that is just perfect...
Though I think we should start think different type of musics to different places. For example Two Steps From Hell - Heart Courage reminds me about plains which are full of grass or things like that...
Places where should be cool or different musics:
City - I suggest : Gothic III - Vengard Theme (Or something like that)
Forest - I suggest : Gothic III - Vista Point (Again Gothic, I really like it...)
Beach - Well I would go for : http://www.youtube.com/watch?v=kB4AvbojT2U
Plain - I suggest : Two Steps From Hell - Heart Courage (Sent by -Kobas-)
Cave - Gothic 2 - The Monastery Underground (I could not find better, Gothic...)
Swamp - I suggest : Gothic - Nature Theme (You know me...)
I think they are too many "Gothic" songs well though they are good. Just my opinion say yours so we can decide.
And if some one could find a good cave music it would be good, I tried to find a good one like 30 minutes before I found something good...
