PS3 Singstar directory help

[Pebbles]

Does anybody know what folder I would put my extracted Singstar files into to get the game to recognize my songs. I am tired of switching disc and looking for an easier way to play all my songs. I looked into placing my extracted files into dev_hdd0/game/SINGSTARFAMILY/USRDIR/downloadsong but it still doesnt seem to recognize it. I have also placed the Errta_0.pkd in its respective folder but still nothing. If anybody can help provide any insight into how the game looks for dlc that would be great. I also extracted the Errta_0.pkd(orginal file in the singstarfamily directory) file from the folder and it seems to have a database of songs with title ids in the xml format of every dlc and disc song released.
