Gaming Last Window - Missing jukebox tracks

[WiiUBricker]

Hi, I finaly beat the game but there are some tracks missing (?) on the jukebox. How can I unlock them?

Did you ever open the secret files at the end of the novel before you beat the game?

Yes I opened the first secret file but let me guess, I messed up, the missing tracks can only be unlocked if none of the secret files were opend during the game, right?
