This might prove an interesting project for a remixer. The music to Civ IV is well known and appreciated but I personally prefer Civ III and would love to see a remix. To be honest I think I would enjoy any of the game's tracks, but SmashFull is probably the best track on the album. Just to keep things interesting though I've also linked to AncEcfull - an intersting song with heavy use of percussion. Sorry for the weird song names, I believe this is what the actual files are called and I've never seen proper names for them.
Thanks in advance to anyone who works on this!
