Classic character select music

[zpsyx9]

I have a custom server and client set up for LANs and I'm trying to get a somewhat classic feel at least with the music. I have downloaded the classic versions of the music both in .mid and .mp3 format. Is there any way to change when certain music is played in the titanium client?

For example, currently the EQ theme plays during loading, character selection, and world loading. In Kunark a different character select theme would play it's first (Idk, 10 seconds), loop the next 30, and play the finale once you select a character, all from the same midi file.
