If this link works, then I'll be pleased, if not I'll give you the list of songs that are in the playlist.

Tell me if you can't see anything, I've got a mix of epic soundtracks (imo) from JRPGs both recent and old, and no there are no Dark Souls musics on there, just because I don't feel that you should find it in a playlist like that.
There are only 9 songs there, if you have any suggestions for some more, tell me and I'll get round to adding it, if I feel like it. I'm not saying you NEED this on, but it will sure make the fights a lot more entertaining and epic.
