It seems as if the song Where Is my Mind was apart of the original Rocksmith (2011) PC Only, and if you own the Rocksmith 2014 Edition, then you can purchase the import tool and get all the songs from 2011 into Rocksmith 2014. But what if your on a mac? As for the first part, you would need to buy Rocksmith (2011 for $29.99) on steam + 9.99 for the disk import tool, just to get all of the song, but there is nothing that mentions cross operating system compatibility. I just wanted to DLC or CDLC this song and it is possibility unavailable on both. Can it be added back to the CustomsForge database? Thanks
