I used to play Rocksmith and then 2014 on my PC, but moved to Playstation 4 so I could use my TV. I'd purchased a lot of DLC in the PS4 over the years, but stopped play for a while. I've since given my PS4 to my child who lives in another state.
I recently decided to try out Rocksmith+ and the song library is pretty unimpressive. So, I loaded up RS2014 in Steam again to get back into it. Of course a lot of the music I liked isn't available to purchase any longer.
Is it at all technically possible to transfer my purchased DLC from my PS4 over to Steam?
