How do I get MP3 music to work on Quake 1 and 2 source ports for PSP?

[LGN-76]

Like the title says.

I'm using the final version of ProQuake for PSP obtained from here:
http://quakeone.com/forums/quake-mod-releases/finished-works/8700-proquake-psp-4-71-a.html

And the Quake 2 port for PSP obatined from here:
https://filetrip.net/psp-downloads/homebrew/download-quake-ii-hardware-05-02-10-f28816.html

I've got them both installed on my PSP and set up the way I want them to be except for the music, because even though I've got the CD tracks ripped to MP3 and on my PSP, I can't figure out what they should be named and where they should go, and neither port tells you that information in their readmes.

Can anyone here help me with getting the MP3s named correctly and put in the right spot so that my Quake 1 and 2 experience on the PSP is complete?

This should help. It has a link to the original Quake soundtrack (in .ogg format, but I don't see much of a difference) with all the files named correctly.
