How to handle voices that overlap musical jingles/other sound effects?

[Gors]

I think as a rule of thumb, you should include all voice clips and sound effects from a game. Sound effects comprise of:

1 - character voice (grunts, quotes);
2 - musical jingles;
3 - sound bits such as explosions, moving cursors, GUI elements.

If your character's voice is merged with a jingle, include it anyway. Include everything that an original soundtrack disc would not include.
