My apologies for my ignorance, but an answers and recommendations would be welcome. I guess the fundamental question I am asking is... is it worth spending about $1000 to buy a new PC (I am a Mac user, and it appears there are almost zero CDLCs available here for a Mac), just so I can get more songs, by artists I like (like Pink Floyd). If the CDLCs are free, and work well with Rocksmith 2014 on a PC, then the answer for me would be YES> Thanks, Dan HI, I use MAC for Rocksmith all of those PC's songs you can convert to MAC, Catch mate http://customsforge.com/topic/33889-how-to-add-custom-songs-on-mac/ Good luck Luke
