The thing is that when i create a different songs by the same artist, sometimes the new song just overwrites the previous one... Physical psarc files are all there, in dlc folder, but in the game only appears some of them.

 

I think that maybe the problem comes with the package id option.. i feel im doing something wrong. Any tips to fix that? 

 

 

Sounds like it. Make sure each song has a different ID.
