You may remix every song, except songs which has an OC Remix and songs which are covered in PRC before. Usual PRC rules apply.
One exception is the source of PRC207: Warlords III: Darklords Rising - Final Victory.
Because that PRC was the first (and hopefully last) which hasn't any entries, you get three points bonus if you remix this source. There's no MID for that source available, for a MP3 file, check http://compo.thasauce.net/rounds/view/prc207
