I don't know what the hell is going on or why, but I failed every time I tried to convert the songs to audio. <!-- s:cry: --><img src="{SMILIES_PATH}/icon_cry.gif" alt=":cry:" title="Crying or Very sad" /><!-- s:cry: --> Nevertheless, I left the MIDI versions on KDev (I shut down the computer, then rebooted, and I was able to get in). Their names are "Dragon Slayer," and "Warrior's Axe." Sorry if they sound a bit rushed, I can do a lot more concentrated work on them if you like.
As for the River Of Fire song, I say use one of the guitar versions* for DarkRaven's map, and for madPaul's, maybe repeat another MP3, IMO HellKeep.mp3 might work best (or use the other guitar version). At this rate, there won't be any new MP3s for a while, so they'll have to wait until v1.1.
