Music doesn't play in Time Crisis [PAL]

[Stone Temple Pilots]

I got my Time Crisis game to work on my PSP thanks to Dark_Alex' patch for 5.00 M33, and even though everything works fine, music doesn't play in the background at all. SFX run perfectly fine without a problem, but if it's possible, I'd like to fix the music problem. Thanks in advance.

I have heard many problems related with popstation in 5.00 M33 and compressed or CDDA PSX games. Try use popsloader to use a older version which this game worked.

Do you know which version played it the best? I've read somewhere that 3.71 was the best POPs but I'd like to know for certain.

You sure the music is even in the game or did you rip it yourself?
