I did not, as I think PS3 is not using the APPID concept found on the mac&PC version(ergo the need to have 1 Official APPID attached to your legal Rocksmith copy). I would recommend: - u make sure the game BLU name is the one where you store the DLCs (maybe multiman shows that in game properties) - u try different official DLCs and CDLCs, as sometime some CDLC have similar IDs and out of this conflict only 1 is displayed, or are corrupted when being converted from PC to PS3..try http://www.ps3iso.com/free-link-downloadable-content/216581-rocksmith-2014-dlc.html after you make an account as she only place I know for original/official/notconverted DLCs - u make sure the game is updated (1.03 i think is the latest version) or you reapply the update
If anyone is still interested in taking out songs from the retail version of Rocksmith please 1.
