Restriction on songs amount?

[Rektalizer]

At some point it stopped adding new songs to the game, yet all old ones are still there and working fine. .dll file is still in the required directory and everything seems the same. Is there maybe some sort of limit of how many songs you can have?

P.S. Removing all songs from folder and adding new did nothing. When I put all the old songs back to the folder it does render them in game fine.
